From the video description
TWO VIDEOS – New video released by the Pentagon late Friday night shows U.S. military aircrafts striking Islamic State terror sites.
“The first attack occurred about 6:45 a.m. EDT when two F/A-18 aircraft dropped 500-pound laser-guided bombs on a mobile artillery piece near Irbil, the capital of Iraq’s Kurdistan region,” the Pentagon said. “ISIL was using this artillery to shell Kurdish forces defending the city, where U.S. personnel are located.”
“Two additional air strikes occurred later in the day, the last at about 11:20 a.m. EDT when four F/A-18 aircraft successfully struck a stationary ISIL convoy of seven vehicles and a mortar position near Irbil, neutralizing the mortar and convoy,” the Pentagon added.
Footage of the strikes shows thick black plumes of smoke rising into the air following a bright white flash after the targets had been hit.
