Update: 2:58 p.m. - The U.S. military has begun a second round of airstrikes against ISIS near Irbil, U.S. officials told CNN on Friday. News of the latest airstrikes came just after the governor of Irbil, Nawzad Hadi, told CNN, that ISIS fighters may be as close as 30 kilometers to Irbil. Air strikes are “very important” because ISIS fighters are well armed and are outgunning the Peshmerga, thanks to the weapons the militants seized from the Iraqi military in Mosul, Hadi said.

(CNN) – U.S. military aircraft have conducted a strike on ISIS artillery that had been used near Irbil, Iraq, Pentagon spokesman Rear Adm. John Kirby said Friday on Twitter.

Two American F/A-18 aircraft dropped 500-pound laser-guided bombs on a “mobile artillery piece” used by ISIS at about 6:45 a.m. ET Friday, Pentagon spokesman Rear Adm. John Kirby said.

ISIS was using the artillery to shell Kurdish forces defending Irbil, Iraq, where U.S. personnel are located, he said.

The commander of U.S. Central Command made the decision to strike under authorization granted him by President Barack Obama, Kirby said.
