ZAMBIAN President Frederick Chiluba flew to the Democratic Republic of Congo on Monday for talks with President Laurent Kabila focusing on the deployment of UN peacekeepers there. Government sources said the talks in Lubumbashi, would review a fragile ceasefire that officials say has largely held since April, when countries sucked into the war agreed a new peace framework. Chiluba is the internationally mandated mediator in the Congo, where civil war erupted in 1998 when mutinous soldiers took up arms, accusing Kabila of corruption and nepotism.
