Gen. Frank McKenzie, a top U.S. commander for the Middle East, told reporters travelling with him that the mortar attack started a fire that was put out. He said no U.S. military personnel were injured, but one U.S. national had a minor injury but returned to work.

Israel said the targets included weapons storage, logistics sites and intelligence centers used by elite Iranian forces in Syria. It also said it destroyed several Syrian air-defense systems after coming under heavy fire and that none of its warplanes was hit.

The Israeli military said its Iron Dome rocket defence system intercepted some of the incoming projectiles, while others caused only minimal damage. There were no Israeli casualties.
