The death toll in an attack by suspected rebels on a school in western Uganda has risen to at least 41, including 38 students, the local mayor said Saturday.

Victims and Abductions

The victims included the students, one guard and two members of the local community who were killed outside the school, Mpondwe-Lhubiriha Mayor Selevest Mapoze told The Associated Press (AP). An unknown number of people were abducted by the rebels, who fled across the porous border into Congo after the raid on Friday night.

Types of Injuries

Mapoze said that while some of the students suffered fatal burns when the rebels set fire to a dormitory, others were shot or hacked with machetes.

Perpetrators and Location

Police said that rebels from the Allied Democratic Forces, who have been launching attacks for years from their bases in volatile eastern Congo, carried out the raid on Lhubiriha Secondary School in the border town of Mpondwe.

Background of the School and Attackers

The school, co-ed and privately owned, is located in the Ugandan district of Kasese, about 2 kilometers (1.2 miles) from the Congo border.

Police said Ugandan troops tracked the attackers into Congo’s Virunga National Park. The military confirmed in a statement that Ugandan troops inside Congo “are pursuing the enemy to rescue those abducted.”

The ADF has been accused of launching many attacks in recent years, targeting civilians, in remote parts of eastern Congo.

The ADF has long opposed the rule of Ugandan President Yoweri Museveni who has been in power since 1986.

The group was established in the early 1990s by some Ugandan extremists, who said they had been sidelined by Museveni’s policies. At the time, the rebels staged deadly attacks in Ugandan villages as well as in the capital, including a 1998 attack in which 80 students were massacred in a town not from the scene of the latest attack.

A Ugandan military assault later forced the ADF into eastern Congo, where many rebel groups are able to operate because the central government has limited control there.

The group has since established ties with the Daesh terrorist group.

Reactions and Condemnations

In March, at least 19 people were killed in Congo by suspected ADF extremists.

Winnie Kiiza, an influential political leader and a former lawmaker from the region, condemned the “cowardly attack” on Twitter. She said “attacks on schools are unacceptable and are a grave violation of children’s rights,” adding that schools should always be “a safe place for every student.”

Ugandan authorities for years have vowed to track down ADF militants even outside Ugandan territory. In 2021, Uganda launched joint air and artillery strikes in Congo against the group.
