Due to a crackdown on non-state media, everything in Libya is very uncertain. There are two very disturbing updates from Al Jazeera, however:
11:00pm: Libyan state TV says “security forces have begun an extensive operation against dens of vandals”.
10:59pm: Libyan city of Misratah, east of Tripoli, is latest to be attacked by airstrikes. Heavy artillery fire devastates buildings as tanks roll into the city, witnesses tell Al Jazeera.
