Two Ugandan rebels shot a British man dead and wounded three people when they attacked a group of tourists in northwestern Uganda, officials said Tuesday. The man who was killed had gone to help other tourists whose vessel had capsized in the Murchison Falls National Park, 230 kilometers northwest of the capital, Kampala, Ugandan army spokesman Lt. Chris Magezi said. After the river accident, they were driving in a vehicle when they came across two Lord's Resistance Army rebels, who "fired on the vehicle," instantly killing the British man, who had been driving, Magezi said. "The rebels robbed everything. They abducted the rest of the people in the vehicle during the ambush, but we have rescued them," he said. Three tourists injured in the attack were being treated in Gulu Independent Hospital, in the main northern Uganda town of Gulu, he said. The Lord's Resistance Army is fighting a 19-year insurgency in northern Uganda and in the past month its members have killed three aid workers, for the first time in the conflict.
