Libya's state news agency says three explosions outside a courthouse in the eastern city of Benghazi have wounded three people and caused some damage to the building's fence and surrounding structures.

LANA says three devices went off early Friday. It wasn't clear who was behind the attack.

Security official Aghdour bin Zablah says the explosives were thrown out of a passing car.

The attack came hours after a failed prison break in Benghazi during which prisoners and guards exchanged gunfire. The shooting killed three prisoners and three guards.

Nearly seven months after the fall of Moammar Gadhafi, Libya is struggling to bring back security. Armed militias that fought Gadhafi's forces for months are refusing to lay down their arms.
