Fighting between Liberian rebels and pro-government forces resumed at the weekend in northern Liberia, diplomatic sources said on Tuesday. The fighting occurred when the Liberians United for Reconciliation and Democracy (LURD) rebel group, which has been fighting to topple President Charles Taylor since 1998, staged an attack in Lofa County a week after the government announced that it was fully in control of the area, the sources told IRIN from the capital, Monrovia.
