Four workers were killed and three firemen injured in a gas pipe explosion on Saturday at Kuwait's largest refinery of Mina al-Ahmadi, an industry source told AFP.
"Based on initial information, the four workers are Asian," said the source who asked not to be named. "The explosion was caused by a leak in a gas pipe."
Mina al-Ahmadi is the largest of three refineries in OPEC member Kuwait, with a refining capacity of over 460,000 barrels per day. The other two at Shuaiba and Mina Abdullah have a combined capacity of around 450,000 bpd.
It was not immediately clear if the explosion would affect Kuwait's crude exports.
