A Ugandan and two foreign tourists have been killed in an attack by suspected Islamist rebels from the Allied Democratic Forces in a national park, police say. The ADF began as an uprising in Uganda but has been based in the Democratic Republic of Congo since the late 1990s. "We have registered a cowardly terrorist attack on two foreign tourists and a Ugandan in Queen Elizabeth National Park. The three were killed, and their safari vehicle burnt," police spokesman Fred Enanga said on social media platform X. Enanga said they were pursuing suspected ADF members, and Uganda's police posted on its X account a picture of a burning four-wheel-drive vehicle. The police did not give a precise location for the attack. The national park's western boundary is the shore of Lake Edward, which separates Uganda from DR Congo. Bashir Hangi, spokesman of the Uganda Wildlife Authority, said the attack took place on Tuesday evening. The wildlife authority said in a statement the one tourist was from South Africa and the other from the United Kingdom. Rebels from ADF have previously carried out attacks in the area and across the border in DR Congo where they have bases. Uganda and DR Congo launched a joint ground and air operation against the ADF in December 2021 to eliminate them from eastern DR Congo. Uganda says it has succeeded in killing more than 560 fighters and destroyed their camps. Last week, ADF fighters killed at least one man and injured another when it ambushed a truck in western Uganda. Australian Associated Press
