A health official in Libya's second largest city of Benghazi says seven people have been killed in clashes between protesters and former rebels aligned with the military.

The doctor in Benghazi's main hospital said the gunfight also left 37 people wounded. He gave no further details about the injured.

A security official in Benghazi says clashes erupted Saturday after protesters stormed a base belonging to Libya Shield, a grouping of pro-government militias tasked to maintain security.

Both officials spoke anonymously because they were not authorized to speak to the media.

The protesters were demanding the gunmen to lay down their weapons and come under the full authority of Libya's security forces.

Benghazi was also the site of the Sept. 11 attack that killed Ambassador Chris Stevens and three other Americans.
