UGANDAN army troops shelled Rwandan positions overnight at an airport near rebel-held Kisangani in the northeast of the Democratic Republic of Congo, a Rwandan officer said on Tuesday. The incident came three days after bloody clashes in Kisangani between the erstwhile allies backing rebels against the government of President Laurent Kabila, and followed an agreement on Monday by the two countries to withdraw troops in and around the city. The agreement came after representatives of the two governments and a UN Security Council delegation, led by US ambassador to the United Nations Richard Holbrooke, met at Ugandan President Yoweri Museveni’s Rwakatura home in western Uganda. It followed clashes on Friday in which at least 15 civilians died and another 50 were injured.
