A truck bomb attack in Libya's coastal city of Zliten killed at least 50 people on Thursday.

The incident occurred at a police training center, al-Jahfal, 160 km from capital Tripoli.

Four local hospitals are functioning under the state of emergency since the attack occurred. Victims are being carted to hospitals in the capital as the local hospitals are working under pressure and can't accommodate any more people. 

As many as 400 police recruits were exercising in the open when a water truck laden with bombs attacked the training academy, a witness told BBC. There has been no confirmation about whether the truck exploded at the gate or inside the academy.

The truck bomb was a suicide attack, BBC quoted UN Special Representative to Libya Martin Kobler as saying.

The Libyan Army is currently battling Islamic State of Iraq and the Levant (ISIL) in the country's biggest oil ports, Es Sider and Ras Lanuf. The fighting has spread to five tankers, which have been on fire since Wednesday, 6 January. 

The Petroleum Facilities Guards said that they are still in control of the two ports where 30 ISIL fighters and at least nine gaurds have died, reported Reuters
