The head of Interpol in Uganda says an Islamic extremist leader who was arrested in Tanzania will be extradited to Uganda after Tanzanian authorities agreed to cooperate.

Asan Kasingye told The Associated Press Tuesday that Jamil Mukulu appeared Friday in a Dar es Salaam court, charged with multiple counts of murder, after his extradition papers were filed.

Mukulu is the Ugandan leader of the Allied Democratic Forces, or ADF, an armed group that originated in Uganda but which now operates in eastern Congo.

The ADF is accused of carrying out massacres in Uganda as well as in parts of eastern Congo, including savage killings earlier this month near the town of Beni in Congo's North Kivu province.
