UGANDAN troops killed 18 Rwandan Hutu extremists and captured four others, including one believed to have taken part in the murder of eight foreign tourists on March 1, the state-owned New Vision reported on Monday. The paper reported that Lieutenant Colonel Benon Biraro, the overall commander for western Uganda, said a clash between the troops and the rebels occurred in the Virunga National Park in the neighbouring Democratic Republic of Congo. The newspaper did not say when the fighting took place. A gang of more than 100 Rwandan Hutus — renegades from their own country’s civil war of 1994 — kidnapped 14 gorilla safari tourists at the Buhoma camp in the remote Bwindi forest reserve on Uganda’s south-west border with the DRC on March 1. They killed four Britons, two Americans and two New Zealanders as well as four Ugandan guides, while six of the abducted foreigners survived.
