The site of a Sunday morning car bomb attack near a police station in Libya's eastern city of Benghazi.

Three police officers were wounded in the latest of a string of attacks on security personnel, though officials at the scene said there were no deaths.

One police witness said the explosion was caused by a home-made bomb attached to the bottom of a parked police car.

The Libyan government is struggling to control a rising tide of attacks by area militias.

Benghazi has been hit by several bombings and other attacks this year - most notably, an attack on the U.S. consulate in September that led to the death of U.S. ambassador Chris Stevens.
