Yemen's armed Houthi movement said on Wednesday it had launched a drone strike on a facility belonging to oil giant Saudi Aramco in southern Saudi Arabia - though the company said its plants there were operating "normally and safely".
The Houthis' Al-Masirah TV channel did not say when the attack took place or give details of any damage.
"The air force announced the execution of air strikes with the Qasef-1 aircraft on Aramco in Jizan (province)," the channel said on its Twitter account, referring to a drone the Houthis unveiled last year.
Saudi Aramco operates a 400,000-barrel-per-day refinery in Jizan, part of a new economic city on the Red Sea.
Al-Masirah said the Houthis had also launched an attack with the same model of drone on the airport of Abha in neighboring Asir province.
