On 16 June 2023 rebels of the Allied Democratic Forces (ADF), a jihadist group speculatively linked by analysts to the Islamic State, attacked a secondary school in Mpondwe, a town in western Uganda's Kasese District on the border with the Democratic Republic of the Congo. 42 people were killed, including 38 students; 8 were injured.

On Saturday morning, Ugandans woke to unsettling news of a militant attack on a boarding school in the west of the country. Authorities say 37 students were killed. Five others, including a security guard who tried to stop the violence, also died. The militant Allied Democratic Forces (ADF) are thought to be responsible for the killing.

At least 41 people were killed in an attack on a school in western Uganda, a local mayor said on Saturday. According to police, the Lhubirira secondary school in Mpondwe was raided by members of the Allied Democratic Forces (ADF) — a Ugandan group based in eastern Congo that is aligned with the Islamic State — late on Friday.

Officials and witnesses said guns and knives were used in a grisly late-night assault and dormitories set ablaze at Lhubiriha Secondary School in Mpondwe. Police and army officials blamed the ADF, one of the deadliest militias over the border in DR Congo's strife-torn east, which the Islamic State group has called its local offshoot.
