Attack on police training centre in Libya kills 65

At least 65 people were killed when a truck bomb hit a police training centre in the Libyan town of Zliten on Thursday.

Dozens more were injured in the attack, which happened as hundreds of recruits were gathering for a graduation ceremony.  

The training centre had been a military base during the rule of ousted Libyan leader Moammar Gaddafi.

The bomb attack comes after four oil storage tanks were set ablaze during deadly fighting as the Islamic State group tries to seize export terminals.

The fires broke out at key terminals in al-Sidra and Ras Lanouf, located in the so-called "oil crescent" along Libya's northern coast.

The Islamic State group has been trying for several weeks to push east from its coastal stronghold of Sirte, and officials have warned of crippling consequences if the extremists manage to seize control of Libya's oil resources.

Libya descended into chaos following the 2011 ouster and killing of longtime dictator Gaddafi.

It has had rival administrations since August 2014, when an Islamist-backed militia alliance overran Tripoli, forcing the government to take refuge in the east.

The United Nations is pressing both sides to accept a power-sharing agreement it hopes will help to reverse IS's territorial gains.

Oil is Libya's main natural resource, and the country sits on reserves estimated at 48 billion barrels, the largest in Africa.

It had a pre-revolt output capacity of about 1.6 million barrels per day (bpd), accounting for more than 95 percent of exports.

But unrest has forced a major slump in production, and output now stands at around 500,000 bpd.
