Saudi Arabia intercepted incoming missiles targeting the kingdom's capital and other regions on Sunday, with falling debris damaging a building belonging to the state-owned oil giant Aramco in Riyadh's financial district.

There was no immediate claim of responsibility for the attack by Yemen's Iran-backed Houthi rebels, who have claimed such attacks in the past.

Meanwhile, the United Arab Emirates said it rescued 22 crew members after a fire broke out aboard a cargo ship in the Sea of Oman, as risks to commercial shipping in the region remain high amid the war in the Middle East.
