Ugandan students' parents submit DNA samples to ID massacre victims

One of Uganda's biggest massacres in recent decades occurred Friday night at Lhubirira Secondary School. Assailants set a dormitory full of boys alight, then attacked a dormitory full of girls, hacking victims to death with machetes and knives.

Six students were also abducted by the attackers, who the authorities say were fighters from an Islamic State-affiliated group based across the border in the eastern Democratic Republic of Congo.

Regional police commander Tai Ramadhan said many of the dead bodies were charred beyond recognition, forcing investigators to use DNA samples from relatives to try to identify them.

Simon Kule, who had come to Bwera Police Station to give a DNA sample, was still looking for his son, Philmon Mumbere.

"So they should help us to know - either these people are still there or they are in the mortuary so that we should prepare in time."

Solomon Mulekya was looking for his daughter, Trephine Kaghuo.

"We are not happy, because we have lost our children," he said. "I'm there in suspense, whether the rebels have taken her or we don't know they killed her along the way."

Authorities said on Monday that 20 suspected "collaborators" of the attackers, including the school's head teacher, had been detained for questioning.
