The Shuaiba oil refinery in Kuwait resumed operation on Saturday, the head of state refiner Kuwait National Petroleum Company (KNPC) said on his Twitter account, after a fire at a heavy oil unit forced a total shutdown last week.

"The Shuaiba refinery has been restarted at a capacity of 120,000 barrels per day and all the units are operating expect those affected," Mohammad Al-Mutairi, chief executive of KNPC, said in a tweet.

The fire at the heavy oil cracking unit at Kuwait's 200,000 barrel-per-day Shuaiba refinery broke out last Monday. There were no casualties reported.

Opec member Kuwait has three refineries, including Shuaiba, with a combined capacity of 930,000 bpd.  - Reuters
