News agency AFP reported that thick plumes of black smoke appeared in the skies after the blast early on Monday

Though the cause was not clear, Pertamina, the oil company whose Balongan refinery in West Java caught fire, said that the blaze started during a lightning storm.

The local disaster agency said one person died of a heart attack following the explosion.
Six people were severely injured and hospitalised and at least 30 others received minor injuries.

Thousands of locals were evacuated from the area after the massive fire.

Fire-suppressing foam was used to douse the blaze at two storage tankers and the company said the fire was ultimately put out on Wednesday afternoon.
