BENGHAZI, Libya — Libyan rebels are saying no to a cease-fire proposal by African mediators.
They object because the plan does not demand that Moammar Gadhafi give up power.
The head of the rebels' leadership council says that Gadhafi and his sons "must leave immediately if he wants to save himself."
A delegation from the African Union had brought the proposal to Libya.
The AU delegates say Gadhafi accepted their cease-fire plan at a meeting late Sunday in Tripoli.
The rebels have the backing of European leaders who are wary of Gadhafi's earlier broken cease-fire pledges.
Gadhafi's forces, meanwhile, battered the rebel-held city of Misrata and its Mediterranean port with artillery fire.
A doctor who lives in the city says six people, one of them a 3-year-old girl, were killed by missiles that slammed into residential areas.
