US President Barack Obama is to make a week-long foreign tour in July that will include Russia, Italy and Ghana, the White House says.

Mr Obama will be in Moscow on 6-8 July for talks that are expected to cover efforts to reduce nuclear stockpiles and non-proliferation.

From Russia he will head to the Group of Eight summit in Italy.

He will then travel to the Ghanaian capital, Accra, on his first trip as president to sub-Saharan Africa.

There had been speculation that Mr Obama’s first presidential trip to the continent might be to Kenya, home to the president’s late father.

The White House said the visit to Russia would provide the chance to deepen engagement on issues including missile defence and security challenges.

‘Promoting development’

Mr Obama and his Russian counterpart Dimitry Medvedev had a good first meeting in Europe last month, agreeing to work together to reduce their countries’ nuclear arsenal, the BBC’s Kim Ghattas reports from Washington.

But a recent thaw has been complicated by a spy scandal at the Nato headquarters and Nato military exercises in Georgia, she adds.

The G8 summit for the world’s leading industrialised nations will take place in the central Italian town of L’Aquila, which was struck by a major earthquake in April.

Mr Obama is due to chair a meeting on energy and climate change at the summit, which runs from 10-12 July.

In Ghana, the White House said Mr Obama and his wife looked forward “to strengthening the US relationship with one of our most trusted partners in sub-Saharan Africa”.

During the visit Mr Obama hopes to highlight the “critical role that sound governance and civil society play in promoting lasting development”, the White House said.

Correspondents say that Mr Obama, preoccupied with foreign policy challenges elsewhere in the world, has not yet articulated a detailed policy for Africa.

Civil liberties groups have reacted angrily to US President Barack Obama’s decision to revive military trials for some Guantanamo Bay detainees.

Mr Obama has previously denounced the Bush-era judicial system, but in a statement said new safeguards would ensure suspects got a fairer hearing.

New rules include rejecting statements obtained from harsh interrogations and limitations on using hearsay evidence.

There are still 240 detainees at the US base in Guantanamo Bay, Cuba.

Barack Obama branded the original military trials an enormous failure

Mr Obama halted the controversial military commissions as one of his first acts on taking office in January, saying the US was entering a new era of respecting human rights.

“It’s disappointing that Obama is seeking to revive rather than end this failed experiment,” said Jonathan Hafetz, a national security attorney at the American Civil Liberties Union.

“There is no detainee at Guantanamo who cannot be tried and shouldn’t be tried in the regular federal courts system. This is perpetuating the Bush administration’s misguided detention policy.”

Kenneth Roth, head of Human Rights Watch, said: “By resurrecting this failed Bush administration idea, President Obama is backtracking dangerously on his reform agenda.”

Campaign statement

On the campaign trail last year, Mr Obama had branded the military commissions “an enormous failure”.

But in the statement issued on Friday, he said he had supported their use as one avenue to try detainees, and in 2006 had voted in favour of them.

He said he had opposed the tribunals used by George W Bush’s administration because they had failed to establish a legitimate legal framework and undermined swift and certain justice.

The extra safeguards for detainees include a ban on evidence obtained by harsh interrogation; restrictions on hearsay evidence; giving detainees more leeway to choose their own lawyers and protecting detainees who refuse to testify, the statement said.

Mr Obama said he was seeking more time so that the new procedures could be implemented.

“These reforms will begin to restore the commissions as a legitimate forum for prosecution, while bringing them in line with the rule of law,” he said.

“This is the best way to protect our country, while upholding our deeply held values.”

But Geneve Mantri, of Amnesty International, said Mr Obama’s message was confusing.

“It was clear from his announcements soon after he reached the White House what he was going to do,” he said.

“Now it is somewhat confusing what the administration’s standard is or what their policies are.”

Zachary Katznelson of Reprieve, which represents a number of Guantanamo Bay detainees, told the BBC that the president was making a “fundamental mistake”.

“He is taking a gravely, truly flawed system, tinkering at the edges and hoping that the world is somehow going to see this as legitimate, as open, as fair – it’s not going to happen,” he said.

In contrast, Mr Obama found support for his decision among his opponents.

“I am pleased that President Obama has now adopted this view,” said Republican Senator John McCain, who lost the presidential election to Mr Obama.

Ari Fleischer, who was George W Bush’s first press secretary, said President Obama “should acknowledge his campaign criticisms were wrong”.

“With some minor changes, he really is following the same path President Bush pursued,” he said.

Pragmatic style

The BBC’s James Coomarasamy in Washington says that although some are disappointed, for others it is further evidence of Mr Obama’s pragmatic style of leadership, one that recognises the need to balance the change he has promised with the reality he has inherited.

Mr Obama has said he wants the Guantanamo Bay camp closed by 2010.

Shortly before his announcement, US officials said that Algerian detainee Lakhdar Boumediene had left Guantanamo Bay for France.

Mr Boumediene was arrested in Bosnia in 2001 and was held for seven years. He was cleared of any wrongdoing in November.
