Gunfire and explosions in Tripoli overnight

From an intermediary, Al Jazeera has received mobile phone footage from a "young Libyan in Tripoli". The footage allegedly was taken in the Zawid Dahmani neighborhood on Tuesday night amid an ongoing security crackdown.

The explosions were at the "TV building" in the neighborhood, our intemediary says.

"(Troops) were patrolling the streets and shooting at random at anyone that was outside, even those on rooftops," he says. "They came in big patrol cars and with no number plates. The patrol and shooting started at 7:00 and continued until 11:00 last night."
