The United States on Monday expressed alarm at "genuine security threats" to Saudi Arabia from Yemen's Iran-aligned Houthis and elsewhere in the region after attacks on the heart of the Saudi oil industry, and it would look at improving support for Saudi defences.
Earlier in the day, the US Embassy in Riyadh said Washington was committed to defending Saudi following Sunday's volley of drones and missiles, including one aimed at a Saudi facility vital to oil exports.
"We continue to be alarmed by the frequency of Houthi attacks on Saudi Arabia. Escalating attacks like these are not the actions of a group that is serious about peace," White House press secretary Jen Psaki said.
"We understand that they face genuine security threats from Yemen and others in the region...We will look for ways to improve support for Saudi Arabia's ability to defend its territory against threats," Psaki told a Washington news briefing.
Saudi-led coalition authorities said most of Sunday's drones and missiles were intercepted en route to their targets and there were no casualties or property losses from the attacks.
