Militants led by the Islamic State of Iraq and the Levant (ISIL) have seized a vast swathe of territory in northern Iraq since overrunning the city of Mosul on June 10.
As a result of the fighting, the Baiji refinery in Salaheddin province has been shut down and the supply route to Iraq's semi-autonomous Kurdish region cut off.
The fuel shortage has caused long queues to form at gas stations in Kurdish cities.
