A car bomb killed a police officer in the Libyan city of Benghazi on Tuesday, an official said, the latest violence to hit the cradle of the 2011 revolt that ousted dictator Moamer Kadhafi.
"A bomb was planted in the car of Sergeant Salah Miftah Wizry," said the security official on condition of anonymity.
"The car exploded while he was coming home from a restaurant." He had died before reaching the hospital, he added.
The night-time explosion shredded the base of the driver seat, leaving nothing but stuffing and crumpled metal inside the car, an AFP photographer at the scene said.
