Air Force planes dropped roughly 140 munitions on a “very broad” gathering of ISIS fighters in the desert in Syria early Sunday morning.

U.S. Central Command said that its warplanes conducted “dozens” of airstrikes on more than 75 sites, including known “ISIS leaders, operatives and camps.” The attacks used B-52 bombers, F-15 fighters and A-10 Warthogs, which have already been flying over the country this month for other attacks.

U.S. military aircraft struck 75 ISIS-related targets in Syria on Sunday, just hours after the government of Bashar Al-Assad fell to rebel forces, according to the White House.
