David Cameron: "You live and you learn and believe you me, I have learnt."
David Cameron has told MPs that "with hindsight" he would not have hired ex-News of the World editor Andy Coulson.
In the closest he has come to an apology, the PM said: "Of course I regret, and I am extremely sorry, about the furore it has caused."
Amid stormy Commons scenes, Labour leader Ed Miliband accused the PM of a "catastrophic error of judgement".
Mr Cameron returned early from a trip to Africa to make an emergency statement on the phone hacking crisis.
He said that if Mr Coulson - Mr Cameron's former media spokesman - had lied about phone hacking at his time at the News of the World then he should face "severe" criminal charges. 'Protect himself' He added: "If it turns out I have been lied to that would be a moment for a profound apology, and in that event I can tell you I will not fall short."
And he told MPs that with hindsight "I would not have offered him the job and I expect that he wouldn't have taken it".
But Mr Miliband said this was "not good enough" and repeated questions about Mr Coulson had been met "with a wall of silence" by Mr Cameron's aides.
"The country has the right to expect that the prime minister would have made every effort to know the facts about Mr Coulson, to protect himself and his office," he said.
"This can't be put down to gross ignorance. It was a deliberate attempt to hide from the facts on Mr Coulson."
Mr Cameron also faced a barrage of questions from Labour MPs over whether he had broken the ministerial code by discussing Rupert Murdoch's bid to take control of BSkyB with News International executives such as Rebekah Brooks.
To roars of outrage from the Opposition benches, Mr Cameron replied: "I never had any inappropriate conversations".
He insisted he had taken himself out of the decision-making process entirely - and that his Labour predecessors Tony Blair and Gordon Brown had enjoyed a closer relationship with the Murdoch empire than him.
Serbian authorities say they have arrested Goran Hadzic, the last remaining fugitive sought by the UN war crimes tribunal in The Hague.
Mr Hadzic, 52, is wanted for atrocities committed in the 1991-1995 war in Croatia. He led Croatian Serb separatist forces.
The arrest comes less than two months after Serbia caught former Bosnian Serb military commander Ratko Mladic.
Mr Hadzic is charged with the murder of hundreds of Croats and other non-Serbs.
Serbian President Boris Tadic confirmed the arrest at a news conference.
He said Mr Hadzic was detained early on Wednesday in the mountainous Fruska Gora region, north of Belgrade, near his family home. He had always been presumed to be hiding there, the BBC's Mark Lowen reports from Belgrade.
Mr Hadzic went into hiding seven years ago, shortly after the sealed indictment against him was delivered to the government in Belgrade.
He may be transferred to The Hague within days. Gen Mladic was arrested on 26 May and flown to The Hague on 31 May.
EU leaders congratulated Serbia for capturing Mr Hadzic, calling it a signal of Serbia's commitment to "a better European future". Mr Tadic has made joining the EU a key goal of Serbian foreign policy.
The first Guantanamo detainee tried in a US civilian court has been found not guilty of all but one of 286 terror charges over the 1998 bombings of US embassies in Africa.
Tanzanian Ahmed Ghailani, 36, was found guilty of conspiracy to damage or destroy US property with explosives.
But he was cleared of many other counts including murder and murder conspiracy.
Ghailani faces a minimum of 20 years in prison. The verdict comes as the US weighs other civilian terror trials.
The BBC's Iain Mackenzie, in Washington, says the verdict will be seen as a huge blow to the Obama administration and its pledge to try Guantanamo suspects in civilian courts.
Officials will now be concidering how to proceed, but it could mean the controversial prison remains open for some time to come, our correspondent adds. Witness barred The attacks on US embassies in Tanzania and Kenya killed 224 people and were one of al-Qaeda's first international shows of strength.
Four accused co-conspirators were convicted over the bombings in 2001 and sentenced to life in prison, but the Ghailani case concludes the first test of the Obama administration's decision to try some Guantanamo inmates in civilian courts rather than in military tribunals.
Nigerian military rescue 19 hostages in Niger Delta
Nigerian troops have rescued 19 hostages kidnapped by militants in the Niger Delta this month, officials say.
Two Americans, two Frenchmen, two Indonesians and a Canadian were freed along with 12 Nigerians in a land, air and sea assault, said officials.
Security sources told the BBC the freed hostages were euphoric.
The operation was the first successful rescue of foreign captives in the Delta without any of the hostages being killed in the process.
It is not clear exactly where the operation was carried out, nor whether any militants were killed or wounded.
The foreigners were captured on 8 November, when gunmen attacked an oil rig belonging to London-based Alfren PLC.
The eight Nigerians were seized on an ExxonMobil platform in Akwa Ibom state a week later, in an attack claimed by Mend, a military group operating in the Delta.
Canada and France have both expressed their relief that the citizens are free and thanked the Nigerian authorities for their efforts.
The BBC's Caroline Duffield in Lagos says the rescue operation marks a change in tactics by the Nigerian military, who worked in close co-operation with local contacts to free the captives.
Violence in the oil-rich Delta region has subsided since last year.
In the past, militants have cut the country's oil production by one-third, causing a spike in global oil prices.
The government and many oil militants reached a ceasefire agreement last year in exchange for cash payouts and job training - but a small faction of Mend has resumed the kidnappings.
There were always fears that a new generation of militants would emerge which would ignore the ceasefire, says our correspondent.
There are also signs the amnesty is faltering, following a firebombing attack on the home of presidential adviser Timi Alaibe last week, she adds.
Mend says it is fighting so that more of Nigeria's massive oil wealth is used to benefit the Niger Delta area which produces the oil.
But criminal gangs have taken advantage of the region's instability to make money from ransoms paid by oil companies, and stealing oil.
The US has voiced concern about Iran's "negative influence" on Afghanistan, after Afghan President Hamid Karzai admitted receiving cash from Tehran.
White House spokesman Bill Burton urged Iran to play a more positive role.
Mr Karzai has denied any wrongdoing, saying the cash was part of a "transparent" process to help to run the president's office.
He was responding to a report that Iran had been passing bags stuffed full of cash to his aides.
Mr Burton told reporters that the American people and the global community had "every reason" to be concerned about Iran trying to have a "negative influence" on Afghanistan.

Cash is king in Afghanistan and so, in many respects, the news that Iran handed over hard currency is unsurprising.
But his admission will do little to reassure some of his foreign supporters who have been concerned at corruption within his government, and Tehran's growing influence in the country.
And his lack of precision didn't help matters - "once or twice in a year, Iran has given five hundred, or six hundred, or seven hundred thousand euros," he said, leaving some to ask - where did the money go, and did all of it make its way into the finance ministry's coffers?
Despite receiving billions of dollars in aid, Afghanistan remains one of the poorest countries in the world.
"[Iranian officials] have a responsibility just like all their neighbours to try to have a positive influence on the formation of a government there, and to ensure that Afghanistan is not a country where terrorists can find safe harbour, or where attacks can be planned on their soil."
The White House spokesman added that Barack Obama's administration had seen the reports about Iran's payments, but declined to give any further details.
His comments come just hours after Mr Karzai admitted that his chief of staff, Umar Daudzai, had received cash.
"The government of Iran has been assisting us with five or six or seven hundred thousand euros once or twice every year, that is an official aid," he said.
He said he had discussed the issue with former US President George W Bush.
"This is nothing hidden. We are grateful for the Iranian help in this regard. The United States is doing the same thing, they're providing cash to some of our offices." 'Slush fund' The story came to light in a New York Times report which claimed that a large bag of euro notes had been passed to Mr Daudzai at the end of an official visit to Iran by Mr Karzai.
The report quoted officials as saying a stream of payments totalling millions of dollars had been used to secure their loyalty of Afghan politicians, tribal elders and even Taliban commanders

The Iranian embassy in Kabul strongly denied the report, describing the claims as "ridiculous and insulting".
"Such baseless speculations are being spread by some Western media outlets in order to confuse public opinion and damage the strong ties between the governments and nations of the Islamic republics of Afghanistan and Iran," a statement said.
But Francesc Vendrell, a former EU envoy to Afghanistan, said the practice of receiving cash donations was far from unusual.
"Many governments that hope to court influence are paying and providing money to the president's office in what I would call a slush fund," he told the BBC.
"This has been going on since the very beginning, and the Americans are very much in the vanguard. So I'm not surprised the Iranians are doing it."
He added that the payments were symptomatic of the West's failure to establish a proper government in the country.
Meanwhile, Nato said on Monday that at least 15 militants had been killed in an overnight air strike in southern Helmand province.
Some unconfirmed reports said civilians had died in the attack. The Helmand governor's office told the BBC they could neither confirm or deny whether those who died in the incident were civilians, and an investigation was under way.
There were initial complaints about the condition of the athletes' village
India is to probe allegations of corruption and mismanagement at the Commonwealth Games in Delhi.
Investigators will look into the awarding of contracts and how the work was supervised.
Former Auditor-General VK Shunglu is to look at all aspects of the event's organisation and planning.
The Games were initially beset by construction delays and complaints about the athletes' accommodation, but were later hailed as a success.
After the troubled start, Commonwealth Games head Mike Fennell praised the event as competition drew to a close.
Despite that praise, India's prime minister said an investigation was needed into an event which became a global story for the wrong reasons.
"The government has decided to constitute a high-level committee under... VK Shunglu to look into all matters relating to organising and conduct of the Commonwealth Games 2010," said a spokesman for Prime Minister Manmohan Singh.
Investigators are due to visit the Games' organising committee on Monday to audit its accounts.
With just days before the Games opened, workers were racing to finish the athletes' village. Some teams initially held back their athletes after reports emerged of dirty bathrooms and exposed wiring and flooding. BBC WORLD
The BBC's Duncan Kennedy says hundreds of Australians have travelled to Rome to witness the Pope canonise Mary MacKillop
Pope Benedict XVI has officially recognised Australia's first saint, Mary MacKillop, a Melbourne-born nun who worked with needy children.
She was canonised with five others, including Brother Andre, a Canadian monk credited with miraculous healings.
MacKillop, who died in 1909, clashed with senior clergy and was briefly excommunicated, in part for exposing a sex-abusing priest.
Thousands of Australians are in Rome to witness the ceremony.
Pope Benedict XVI, canonised the six saints in St Peter's Square in front of some 50,000 people.
He declared that "throughout the Church they be honoured devoutly among all the saints". Commitment Among those attending the Mass were hundreds of nuns from the order MacKillop helped found, the Sisters of St Joseph of the Sacred Heart.
"We've always believed that Mary was a saint," said 65-year-old Moya Campbell, a member of the order.
Father Thomas Casanova, a priest from New South Wales and a distant relative of MacKillop, said it was a momentous occasion.
"I've been looking forward to this since I was a child," he said.
Others wanted to recognise MacKillop's lifetime of commitment to poor people, including Australia's Aboriginal population.
"She supported Aboriginal people because she believed in supporting people who were disadvantaged," said pilgrim Melissa Brickell.
For anyone to become a saint, the Church has to recognise their intermediary role in two miracles.
Australians were prominent at the Vatican ceremony
In MacKillop's case, both were in relation to people who were ruled to have been cured of cancer after praying for the nun's assistance.
Veronica Hopson was the first person MacKillop is said to have healed - she recovered from leukaemia in 1961.
On Sunday she told Australian TV: "I feel very fortunate that I was given the opportunity to live my life, have a family, have grandchildren, so that's a miracle."
Kathleen Evans, the second person MacKillop the nun is credited with healing, recovered from cancer in 1993. She attended the canonisation Mass and carried relics of St Mary to the altar.
"I think she would be delighted to see so many people looking at their own lives and considering how they can live better and care more," Ms Evans said in a statement.
Many Canadians were also in St Peter's Square to honour Brother Andre, who is thought to have healed thousands at his monastery in Montreal.
"He was wonderful. He healed many," Anna Diliddo, a teacher from Toronto, told AFP news agency. Religious celebrity
Four steps to sainthood
The process, which cannot begin until at least five years after the candidate's death, involves scrutinising evidence of their holiness, work and signs that people are drawn to prayer through their example:
First stage: individual is declared a 'servant of God'
Second stage: individual is called 'venerable'
Third stage (requires a miracle attributed to candidate's intercession): beatification, when individual is declared blessed
Fourth stage (requires a further authenticated miracle): candidate is canonised as a saint for veneration by Church
Mary MacKillop was excommunicated in 1871, but the Church later exonerated her. She was eventually put on the road to sainthood by Pope John Paul II, who beatified her in 1995.
Australian Foreign Minister Kevin Rudd, who attended the Mass, has described MacKillop as "an extraordinary Australian woman".
Because of her role in exposing clerical abuse, some have called for MacKillop to made a patron saint of abused children.
In recent years, there has been a wave of cases around the world in which Church authorities failed to deal properly with priests accused of child abuse, sometimes just moving them to new parishes where more children were put at risk.
Brazil's presidential election will go to a second round after Dilma Rousseff failed to win an outright victory in Sunday's voting.
With 98% of votes counted, President Lula's former cabinet chief has 47% with Jose Serra trailing on 33%.
The two will contest a run-off vote in four weeks' time.
A strong showing by the Green Party candidate, Marina Silva, who polled 19%, may have cost Ms Rousseff a first-round win.
"We can confirm there will be a second round in the presidential elections," Ricardo Lewandowski, the president of the High Electoral Tribunal, told reporters in Brasilia late on Sunday.
Workers Party candidate Dilma Rousseff is the favoured successor to President Luis Ignacio Lula da Silva, who has completed two terms, and cannot run for a third.
Until just a few days ago, a second round had seemed unlikely. But Dilma Rousseff lost support late in the campaign.
The votes of the third-placed candidate will be crucial in deciding the outcome.
Marina Silva of the Green Party, a devout Christian, enjoyed a late surge in support - some of which appears to have come from evangelical Christians who turned away from Dilma Rousseff amid concerns about her stance on abortion.
Addressing supporters, Ms Rousseff said she welcomed the opportunity to explain her policies in more detail.
Analysts say Ms Rousseff ran a careful campaign, benefiting from Mr Lula's widespread popularity and the country's booming economy.
She was a frontrunner for much of the campaign.
Centre-left candidate Jose Serra, the Social Democratic former governor of Sao Paulo state, had seen a boost in his support after corruption allegations surfaced involving a former aide of Ms Rousseff.
Brazil, one of the world's most populous democracies, was also choosing local and national representatives.
A fireworks display in Berlin marks the anniversary
Germany has been celebrating the 20th anniversary of its reunification.
Chancellor Angela Merkel led the official celebrations, hosted by the northern city of Bremen and attended by tens of thousands of people.
Capitalist West and communist East Germany merged on 3 October 1990, nearly a year after the fall of the Berlin Wall which divided them.
Sunday is also the day Germany makes the last payment on debt stemming from reparations imposed after World War I. 'Solidarity tax' Mrs Merkel was joined by many leading German and international figures in Bremen to mark one of the 20th Century's historical turning points.

We have been able to rebuild so quickly and make Germany a country that is respected in the world”
End QuoteAngela Merkel
German President Christian Wulff told the assembled dignitaries: "We remember the momentous day that a people experience only rarely. I bow before everyone who fought for freedom... your courage moved the world."
He called for a "new solidarity" that encompassed Christianity, Judaism and Islam.
"We must not allow the cementing of prejudice and exclusion," he said.
On the eve of the anniversary, US President Barack Obama passed on his congratulations and said Germany was "one of our closest allies and greatest friends".
He said the US honoured "the courage and conviction of the German people that brought down the Berlin Wall, ending decades of painful and artificial separation".
Mrs Merkel, who was brought up in the East, praised former East Germans for fighting for their freedom.
She added: "At the same time, there was a huge wave of solidarity from the people in West Germany. It is thanks to these joint efforts that we have been able to rebuild so quickly and make Germany a country that is respected in the world."
Angela Merkel on people still leaving Eastern Germany
Since the two countries became one, more than 1.5 million people have migrated west.
The BBC's Stephen Evans in Berlin says opinion polls show some unhappiness in the west about the so-called "solidarity tax" on incomes to pay for eastern reconstruction but on both sides of the country the polls indicate a big majority in favour of a united Germany.
However, not everyone welcomed the reunification festivities.
Thousands of police were deployed in Bremen on Saturday as some 1,800 mainly left-wing activists marched through the city in protest. The demonstration passed off peacefully.
Sunday also marks the final day of German reparations for World War I.
A last payment of 70 million euros (£60m) will draw the debt to a close.
In 1919, the victorious allies wanted to ensure Germany would not be capable of war for many years and set reparations at the equivalent of 100,000 tonnes of gold.
But the plan backfired, with modern-day historians claiming the decision was a key factor in the lead-up to World War II.
