The Houthi movement in Yemen has confirmed that one of its drones has attacked a refinery owned by the Saudi oil company, Aramco. The attack took place on Wednesday.

Meanwhile, Saudi Arabia's Aramco has said a fire broke out at one of its refineries  in Riyadh on Wednesday. According to the company, the fire was successfully  contained, and only caused a limited amount of damage to the plant.

A tweet on the account of the Houthi-run television channel al-Masirah, read: “Our air force drone has targeted the refinery of ARAMCO company in Riyadh.”

A Houthi military spokesman has confirmed that the operation by the drone air force is part of a new campaign by Yemen to deter the Saudi military aggression.

Aramco announced that its fire control teams and the Saudi civil defense had contained a limited fire that erupted in early evening in storage containers at its refinery in Riyadh.

It tweeted that the fire had not affected the activities of the refinery and there were no casualties. It said an investigation would be opened to determine the causes of the fire. A military coalition led by Saudi Arabia and the United Arab Emirates attacked and invaded Yemen in 2015, allegedly to restore to power Yemen's fugitive president, Abd Rabbo Mansour Hadi, a close ally of Riyadh.
