UN Secretary General Kofi Annan asked the Security Council on Tuesday to force the Rwandan and Ugandan armies out of the Democratic Republic of Congo. He asked the council, “acting under Chapter Seven of the UN Charter,” to demand that Rwandan and Ugandan forces withdraw immediately from the war-shattered city of Kisangani, and from the whole DRC “promptly thereafter”. Chapter Seven gives the council powers to impose a range of economic and diplomatic sanctions upon a UN member state, and to use demonstrations of force, blockades and other military operations if sanctions are not enough.
