A fire at a small refinery in eastern Iran's Birjand special economic zone caused two explosions on Sunday (December 10) and remains out of control, Iran's state media said.
No casualties were reported but the damage has yet to be assessed, state media said, adding that all 18 reservoirs at the refinery have caught fire.
Iran's semi-official Fars news agency said the initial stages of the fire had consumed 1.5 million litres of fuel.
