"We are determined to continue our movement until the departure of (Prime Minister) Ali Zeidan," said Osama Kaabar, a leader of the militias who had promised to lift their siege if the law was passed.
The General National Congress, under pressure from the gunmen, yesterday voted through the controversial law to exclude former Gaddafi regime officials from public posts in a move that could see the premier removed from office.
"The adoption of the law on political exclusion is a major step in the right direction. But we will take our time to examine certain aspects of the law," said Kaabar who is also a vice president of the Superior Council of Libyan Tuwwar (revolutionaries).
"On the other hand we are determined to bring down the government of Ali Zeidan," he said, accusing the premier of "provoking the thuwar," former rebels who fought Kadhafi's forces during the 2011 armed uprising.
