Fred Enanga, Ugandan Police Spokesman said government was seeking the extradition of the leader of an Islamist armed group responsible for the massacre of civilians in Uganda and Congo.

He said on Thursday in Kampala that police officials have been sent to facilitate the extradition of Jamil Mukulu from Tanzania, where he was arrested in late April.

“A team of our officials went to Tanzania early this week with all the necessary extradition papers,” he said.

The spokesman said the rebel leader was likely to face charges, including murder, rape, kidnapping and the recruitment of children as soldiers.

Enanga said the 51-year-old heads the Allied Democratic Forces-National Army for the Liberation of Uganda (ADF-NALU), which was founded in Uganda in the mid-1990s, moved to eastern Congo because he was under pressure from the government.

The spokesperson said the group was suspected of killing hundreds of people in both countries, including more than 300 people in and near Beni in Congo, late last year.

Violence has ravaged eastern Congo since the 1996-2003 Congo wars, which were sparked by more than a million Rwandans flooding into the region after the Rwandan genocide in 1994.

Dozens of armed groups remain active in the east of the country, including ADF-NALU.

Many of the armed groups terrorize local people in order to have free reign in trafficking with the region’s rich natural resources, according to human rights activists.
