Libya says a huge blaze, engulfing the country's biggest oil storage facility for an international airport in the capital Tripoli, has spread to a second tank.
In a statement released on Monday, Libya’s interim government appealed for international help to try and put out the blaze, which could create a "humanitarian and environmental disaster."
It also called on rival militias to halt their clashes over the control of the airport which began on July 13.
"The government appeals to all concerned parties to immediately stop firing as the situation has become very grave," the statement said.
The airport has been controlled by militias from the town of Zintan since the overthrow of longtime dictator Muammar Gaddafi in a popular uprising in 2011.
The first depot containing more than six million liters of oil was hit by a rocket on Sunday night.
Firefighters have been battling the blaze, but ongoing clashes have forced them to escape from the area.
Libya is currently witnessing one of its worst spasms of violence since the ouster of Gaddafi.
The Health Ministry said on Sunday that two weeks of fighting in the capital has left 97 people dead and over 400 injured.
Nearly three years after the fall of Gaddafi, Libya is still grappling with rising insecurity as the country has been witnessing numerous clashes between government forces and rival militant groups.
The former rebels refuse to lay down arms despite efforts by the central government to impose law and order.
