The US paused its almost two-week run of strikes against Iran for a second night as skirmishes between Yemen's Houthi militants and Saudi Arabia ratcheted up tensions near a global energy chokepoint in the southern Red Sea. The Iran-backed Houthis said they fired missiles and drones at facilities linked to oil giant Saudi Aramco in the port towns of Jizan and Yanbu on Saturday. There was no immediate confirmation from the Saudi government or Aramco.
