Libyan leader Gaddafi survives NATO air strike, son killed

Libyan leader Muammar Gaddafi survived a NATO air strike on a Tripoli house that killed his youngest son and three grandchildren, a government spokesman said on Saturday. The strike, which came hours after Gaddafi called for a ceasefire and negotiations in what rebels called a publicity stunt, marked an escalation of international efforts to prevent the Libyan regime from regaining momentum.
