Four killed in Libya car bomb blast in Benghazi
A car bomb explosion near a hospital in the Libyan city of Benghazi has killed at least four people, officials say.
The blast follows a string of bombings in the eastern city in recent days.
Security remains precarious in Libya since the uprising against long-time leader Muammar Gaddafi, with protests by militias and attacks by Islamists.
