Five people have died in a Daesh attack at the Zueitina oil refinery in southeastern Libya on Tuesday, according to Libya's local news outlets.

Daesh militants attacked the entrance of the facility in the town of Zillah, which resulted in the deaths of two security guards and three militants while four guards managed to escape, the outlets said.

The attack took place two days after the Daesh group released a video threatening the forces of General Khalifa Haftar of the Libya National Army.

Libya has remained beset by turmoil since 2011 when a NATO-backed uprising led to the ouster and death of long-serving President Muammar Gaddafi after more than four decades in power.

Since then, Libya’s stark political divisions have yielded two rival seats of power -- one in Tobruk and another in Tripoli -- and a host of heavily armed militia groups.
