SHARE Three UN peacekeepers have been killed by unidentified combatants in the Central African Republic, the United Nations said, as the country prepares for a general election and fighting continues between rebels and government forces. The news came after a rebel coalition called off a ceasefire and said it would resume its march on the capital and following the arrival of troops from Russia and Rwanda to shore up the government of the resource-rich country. "Three peacekeepers from Burundi were killed and two others were wounded" following attacks on UN troops and Central African national defence and security forces, the UN said in a statement Friday.
