Iran Warns of US Attack as Houthi Strikes Hit Saudi Arabia

Iran warned on Sunday against any new large-scale attack by the United States and its allies, stating it had intelligence that such a move was being prepared. The warning, issued by Iran's military central command on state media, said any attack would trigger sustained retaliation against U.S. bases and interests, with regional allies considered parties to the conflict. The U.S. State Department had issued a security alert on Saturday, citing potential for unforeseen escalation in the Middle East and advising Americans to remain vigilant. The alert came amid ongoing hostilities, including claimed strikes by Yemen's Iran-backed Houthi forces on Saudi Arabia. On Saturday, the Houthis said they had carried out attacks on the Saudi capital Riyadh and a major oil facility in the Red Sea port of Yanbu. Video footage showed a large plume of black smoke near Riyadh's main international airport after explosions were reported overnight. Saudi Arabia did not comment on the incidents or the Houthi claims, though a Saudi-led coalition fighting the rebels stated it had foiled other attacks on the kingdom.
