Yemen's Iran-backed Houthi movement said on Saturday it had fired 14 drones at several Saudi cities, including at Saudi Aramco facilities in Jeddah.
There was no immediate Saudi confirmation. Saudi Aramco, the state oil firm, said when contacted by Reuters that it would respond at the earliest opportunity.
The Houthi military spokesman said in a televised press conference that the group had also attacked military targets in Riyadh, Jeddah, Abha, Jizan and Najran.
The Houthis have intensified their missile and drone attacks at Saudi Arabia this year, while the Biden Administration removed the group from its terrorism designation and urged Riyadh to try harder for an agreement over Yemen.
The Saudi-led coalition attacked Iran-affiliated targets in Yemen on November 17 after intercepting a drone that attempted to attack an airport in Saudi Arabia on Thursday.
The coalition was taking "operational measures to deal with the sources of hostile cross-border attacks," Saudi state news agency SPA reported.
Secret locations of Iranian Revolutionary Guards and Lebanese Hezbollah forces were targeted.
