Armed men have surrounded Libya's foreign ministry demanding that officials who worked for deposed leader Muammar Qaddafi's regime be banned from senior positions in the new administration.
Witnesses were quoted as saying some 30 vehicles, some mounted with antiaircraft guns, surrounded the ministry building in Tripoli on April 28.
A military official said negotiations were under way and no one had entered the offices.
Qaddafi was toppled by Western-backed rebels in 2011, who captured and killed him.
Libya's government is struggling to assert its influence across the country where armed militia's who fought against Qaddafi still control much territory.
