Nobel peace laureate Desmond Tutu met up with former US president Jimmy Carter in Darfur Tuesday to promote peace in Sudan's war-ravaged region.

The two high-profile humanitarians were part of a delegation of prominent statesmen, known as "The Elders", visiting Darfur this week as peace talks are set to start in Libya and the first team of the UN-African Union peacekeeping force is slated for deployment later this month.

The visit also comes days after an unprecedented attack on African peacekeepers in northern Darfur left 10 dead and dozens injured and missing. It was the deadliest assault on AU forces since the 7,000-strong mission was deployed to western Sudan in 2004.

"We are not here on a sightseeing tour. We hope we can do something that will make a significant difference...and bring peace," said South African Archbishop Tutu, according to The Associated Press, after the delegation arrived in El Fasher - the capital of North Darfur province.

Tutu and Carter are leading the delegation which includes billionaire businessman Richard Branson, Graca Michel, wife of former South African president Nelson Mandela, and several prominent former statesmen from Africa.

Delegates will meet with refugees, non-governmental organisations, and officials to facilitate a peaceful solution in Darfur, where some 200,000 people have been killed and more than 2.5 million people displaced since 2003.

Khartoum is widely accused by both Darfurians and the international community of unleashing the pro-government janjaweed militia on Darfurians after rebels from ethnic African tribes in the region rose up against the central government.

US President George W Bush has condemned the violence in Darfur as "genocide."

"Maybe some don't think it's genocide," said Bush on September 25 at the UN Security Council meeting, according to Bloomberg. "If you are mercilessly killed by roaming bands, you know it is genocide. And the fundamental question is, are we in the free world willing to do more?"

Carter said the main goal of the three-day visit to Sudan was to seek free and fair elections in 2009 - the first ever democratic elections in Sudan.
