According to Ugandan authorities, three persons have been detained in relation to a Friday attack on a school that left nearly 40 people dead.
Students from the Lhubiria school in the western town of Mpondwe made up the majority of the victims.
Many died from burns in their dormitories. According to District Commissioner Joe Walusimbi, the arrests were made as a result of tips from locals.
He noted that the Ugandan army was still looking for the fleeing perpetrators, who had reportedly escaped into the Democratic Republic of the Congo.
Recall that at least six people were abducted by the rebels, who fled across the porous border into the Democratic Republic of the Congo after the grisly raid.
It was the deadliest attack in Uganda since twin bombings in Kampala in 2010 killed 76 in an attack claimed by the Somalia-based al-Shabaab group.
Mpondwe-Lhubiriha Mayor Selevest Mapoze said on Saturday while some of the students suffered fatal burns when the rebels set fire to a dormitory, others were shot or hacked to death with machetes.
Mumbere Edgar Dido, 16, said the attackers arrived at his dormitory carrying machetes and guns and opened fire from outside, sending everyone diving under their beds.
