Libya Protests: Growing pressure on Gaddafi regime
Security forces and protesters have clashed in Libya's capital for a second night, after the government announced a new crackdown.
Witnesses say warplanes have fired on protesters in Tripoli.
To the west of the city, sources say the army is fighting forces loyal to ruler Col Muammar Gaddafi, who appears to be struggling to hold on to power.
Journalists are banned from Libya but the BBC's correspondent in Tripoli sent this anonymous report.
