US warns of rapid escalation in Mideast war

RIYADH, Sept 20: The United States warned that fighting between Saudi Arabia and Iran-backed Houthis could "escalate rapidly" after a missile attack targeted Riyadh for the first time since the Yemen conflict resumed.

US President Donald Trump cut short a weekend at Camp David, a secluded presidential complex in rural Maryland, to return unexpectedly to the White House on Saturday.

The White House gave no explanation for the early return, which comes as a new threshold was crossed in the conflict between Saudi Arabia and the Houthis, who control a large part of Yemen and are fighting government forces backed by a coalition led by Riyadh.

Loud explosions rang out on Saturday in the Saudi capital, where AFP journalists saw a fuel tank bearing the logo of oil giant Aramco on fire near the airport.

"This military conflict has the potential to escalate rapidly," the US State Department warned, adding American citizens outside the Middle East should "seriously reconsider travel to and through the region".�" AFP
