Two oil blasts in Iran today killed one person and injured three others.
Iranian media reported the two fire blasts, one at the Shazand Oil Refinery in Arak and the other at the Bibi Hakmieh oil rig, about 800 kilometres south of Tehran.
The first blast was brought under control and left no casualties, said the head of the Shazand Refinery, and everything is back to normal.
At the Bibi Hakmieh oil rig, a fiery explosion occurred when the workers reached a large layer of gas trapped in the oilfield, leaving one person dead and three others injured.
The fire has reportedly been brought under control.
The Bibi Hakmieh oil field was discovered in 1962 and produces 120,000 barrels of crude per day. Last February, the Oil Ministry funded a project to increase production to 250,000 barrels a day.
Iran’s oil and gas sector has been plagued by a rising number of explosions in the past year.
In May, an explosion occurred at the Abadan Refinery while Mahmoud Ahmadinejad was visiting the plant. Four people were killed and at least 20 were injured.
