State media is describing it as "a fire in a canal carrying waste from Iran's Abadan oil refinery," with Iranian official broadcaster IRIB saying, "The refinery's fire department contained the fire and prevented it from spreading to other units."

However, given the extent of the blaze captured in social media circulating videos, and especially given it comes after a tense summer of attacks on tanker and refineries — notably the Sept. 14 Saudi Aramco drone and missile attack — the newest Iran facility fire raises serious question. 

Could the clearly massive Abadan blaze, which Iranian state sources appear ready to downplay, be the result of a Saudi revenge attack?

Though unverified and unconfirmed, Iranian opposition sources are pointing to a potential cyber attack as a possible cause for the fire.
