At least 33 people have been killed and dozens more injured in a double car bombing in the Libyan city of Benghazi.
The first blast struck outside a mosque as worshipers were leaving evening prayers.
Some 10 to 15 minutes later, after security and medical staff had arrived on the scene, a second, more powerful bomb was detonated from a Mercedes parked nearby.
An ambulance was caught in the blast.
The twin explosions have shattered the relative calm that had recently returned to Libya's second city in a country trying to emerge from more than three years of war.
It's not yet clear who was responsible.
