Meanwhile in Free Libya
Armed men have shut down a gas facility in the mountainous western region of the country, predominantly inhabited by members of Libya's Berber minority - also called Amazigh.
The facility taken by the gunmen is near the town of Nalut.
Various groups have blockaded oil and gas facilities in different parts of Libya over the past few months.
The ministry of electricity has warned that the latest closure will lead to severe power cuts.
The BBC's Rana Jawad, in Tripoli, says some in the region's Berber minority fear they will be marginalised as an ethnic group when Libya's constitutional drafting process eventually begins.
The head of Nalut's local council, Salah Ghardaa, told the BBC that the protestors "are fed up with the Libyan Congress's inaction".

The assembly which will draft Libya's new constitution has not yet been formed.
