Iran has started cutting oil production to prevent storage facilities from reaching full capacity amid a U.S.-imposed maritime blockade.

A 346-meter-long tanker, vital to Russian Arctic oil exports, has essentially "disappeared" from ship tracking systems.

A fire that broke out at an oil storage facility in Gyeongsan, South Korea, has been contained, with no casualties reported, according to local authorities.

An oil storage tank in the South Korean southeastern city of Ulsan exploded Monday, leaving one person dead and another injured, officials said.
