The Yemeni Houthis (Ansar Allah movement), supported by Iran, announced a military operation, the target of which was the facilities of the Saudi Aramco oil company in the southern Saudi cities of Jizan and Yanbu.
There has been no official confirmation of this information from Riyadh yet, but eyewitnesses report thick black smoke above the Aramco oil refinery in Jizan.
Earlier, Saudi authorities issued a warning to residents of Jizan and Yanbu due to Houthi threats to retaliate for attacks on their positions this week.
