Militiamen attacked the Libyan Prime Minister's office Tuesday, following the suspension of a rewards scheme for former rebels earlier this year.
Prime Minister Abdulrahim el-Keib was not present when militiamen stormed the building.
At least 15 pick-up trucks mounted with anti-aircraft guns encircled the building, with more militias arriving as the afternoon progressed.
"Since the beginning of the revolution the rebels have not been paid," said Muntasir Sohe, who had joined the crowd watching the scene unfold. "They want their share and have no other choice; they made the revolution, but they don't get paid," he added.
Last month, due to widespread fraud and abuse, the interim authorities suspended a one-off cash payment for former rebels who had fought against Muammar Gaddafi, drawing the ire of fighters who insist they should be paid for their role in last year's insurgency.'
