Amsterdam ? A Sudanese rebel leader has turned himself in to the International Criminal Court to face war crimes charges today for an attack that killed 12 African Union peacekeepers in Darfur in September 2007, the court said.

Bahr Idriss Abu Garda is one of three suspects in the case — the only case prosecutors have launched against rebels in Sudan’s Darfur conflict.

The other two rebel suspects have not been publicly identified, and the court said Sunday it was trying to see whether they would also turn themselves in or if it had to issue arrest warrants against them.

The Hague-based tribunal has also accused Sudanese President Omar al-Bashir of orchestrating war crimes in Darfur. U.N. officials estimate up to 300,000 people have died and about 2.7 million have been displaced since the Darfur conflict began in 2003, pitting mostly ethnic African rebels against government forces and Arabic-speaking militias.
