The Libyan government has said that militias have captured most government ministries in Tripoli, adding that armed men had blocked staff from entering offices.
BBC News reports that militiamen seized the US embassy on Sunday, with videos showing cheering men diving from a balcony into a swimming pool.
Meanwhile, Abdullah al-Thinni [Al-Thani, al-Thanay] (pictured) has been reappointed as prime minister following his resignation last week.
Senior government officials and the elected parliament moved to the eastern city of Tobruk last month for security reasons.
