'Kamikaze' drone assault on Russian oil refinery triggers huge blast and fire

Two drones flying from the direction of Ukraine hit a major Russian oil refinery near the border on Wednesday, the plant said, sending a ball of flame and black smoke billowing into the sky and prompting the plant to suspend production. The Novoshakhtinsk oil refinery in Russia's Rostov region said the first drone struck at 8.40 a.m. (0540 GMT) hitting a crude distillation unit, triggering a blast and ball of fire. The second strike at 0623 GMT was aimed at crude oil reservoirs at the refinery, the largest supplier of oil products in southern Russia, but caused no fire, the plant said. No one was injured.
