Kuwait Oil Company (KOC) on Tuesday emphatically denied rumors buzzing social media sites about purported leakage at oil installations. Smoke that billowed into the skies in south of the country early today originated from the industrial zone in Mina Abdullah, said the KOC in a statement. The KOC operations are proceeding regularly, along with standard safety precautions. The industrial zone witnessed early today a fire that burned a dumping site of used tires that were later dumped with heaps of sand.
