Yemen's Houthi movement said on Monday it had fired 17 drones at Saudi targets, including 10 launched towards Saudi Aramco refineries in Jubeil and Jeddah, according to Al Masirah TV, the main television news outlet run by the Iran-aligned group.
There was no immediate Saudi confirmation.
The Houthis, who ousted Yemen's internationally recognized government from the capital, Sanaa, and now hold most of north Yemen, have kept up missile and drone attacks on Saudi Arabia after Riyadh presented a new peace initiative.
Last month the Saudi-led coalition destroyed two explosive-laden boats that the Houthis planned to use in an "imminent" attack launched from the Red Sea port of Hodeidah, according to Saudi state media.
The coalition in separate statements also said it intercepted and destroyed three armed drones launched towards southern Saudi Arabia, including the city of Khamis Mushait.
The Houthis want the coalition to fully lift its sea and air blockade on areas the group controls.
The conflict, seen in the region as a proxy war between Saudi Arabia and Iran, has caused what the United Nations says is the world's largest humanitarian crisis.

The Houthis say they are fighting a corrupt system and foreign aggression.
