Unidentified gunmen assassinated the police chief of Libya's capital Tripoli Tuesday afternoon, a security source said.
Mohammed Souissi, head of the security directorate of Tripoli, was found dead in his car with his body riddled with bullets, Xinhua quoted the source as saying.
The incident took place in Tajura area in eastern Tripoli.
It was the second such assassination in less than a month in the volatile North African country where unidentified assailants earlier killed Colonel Hassan Kamuka, head of the security directorate of Sabratha.
Libya has witnessed a drastic escalation of violence since the 2011 turmoil which toppled its former leader Muammar Gaddafi. The recent deadly clashes between rival armed factions in major cities like Tripoli and Benghazi were feared to turn into a full-fledged civil war.
