At least five people were believed to have been killed in Libya when forces loyal to Muammar Gaddafi opened fire on protesters.
One resident in the Janzour district of Tripoli said the shootings happened as demonstrators shouted anti-Gaddafi slogans in the Fashloum district, in the east of Tripoli.
Thousands of Libyans were called to a mass demonstration in Colonel Gaddafi's stronghold - in defiance of shoot-on-sight directives issued to the military.
The outpouring of anger in Green Square after Friday prayers was seen as particularly significant as areas loyal to the Libyan leader dwindle.
