Fighting continued to rage in the Liberian capital Monrovia Wednesday, despite a renewed cease-fire call by rebel leaders.

Monrovia has once again woken to heavy fighting between government and rebel forces. Rebel leaders called another cease-fire Tuesday, but this, like previous instructions from the rebel leadership, has not been followed by troops on the ground.

In a telephone interview with VOA Wednesday, the Liberian Information Minister, Reginald Goodridge, said government forces were maintaining pressure on rebel positions, but that mortar shells continued to fall on central Monrovia.

"We are putting tremendous pressure on them in the port area, but they are continuing to launch mortars into the city," he said.

Meanwhile, international aid workers are warning of an impending humanitarian disaster in Monrovia, as supplies dwindle and cases of cholera and child malnutrition rise.
