Iran-backed Houthis in Yemen have carried out a missile and drone attack on oil facilities in neighboring Saudi Arabia.
It comes days after the Saudis proposed a truce to end Yemen's civil war.
A Houthi spokesperson disclosed the attacks on Friday. Saudi Arabia said a projectile struck a petroleum distribution station in the southern city of Jazan, causing a fire that damaged a tank.
Saudi Arabia, which backs government forces in Yemen, called for a UN-monitored nationwide ceasefire on Monday. It also urged the Houthis to launch political negotiations.
Yemen's civil war broke out in 2015. The United Nations says years of fighting have caused "the world's worst humanitarian crisis."
