At least two members of Libya's General National Congress were shot and wounded after protesters stormed its headquarters in Tripoli on Sunday evening, according to congress members.
One of the congressmen, Abdul Rahman Sweihli, was shot in the leg after protesters opened fire on him inside the building.
As his security detail rushed him out, gunmen opened fire on their cars as they were trying to flee, his son Bashir Sweihli told CNN.
No information about the second lawmaker was available.
A GNC member speaking on Libyan TV said lawmakers continued their evening session despite dozens of protesters surrounding the building and pouring gasoline on the walls before they stormed the building.
Other members of the GNC, the country's interim parliament, were assaulted, and some of the women members harassed, lawmakers said.
Young men ransacked the building, and parts of it were set on fire, according to witnesses.
Videos posted to social media sites showed a chaotic scene, with young men setting cars and furniture outside the building ablaze.
