Gaddafi 'son and grandchildren die' in Nato missile strike

Libyan leader Muammar Gaddafi has escaped a Nato missile strike in Tripoli, but one of his sons and three grandchildren under the age of 12 were killed, a government spokesman said.

The strike, which came hours after Gaddafi called for a cease-fire and negotiations in what rebels called a publicity stunt, marked an escalation of international efforts to prevent the Libyan regime from regaining momentum.
