U.S. warplanes carried out targeted airstrikes this morning on ISIS artillery near Irbil, Iraq. In a tweet, the Pentagon spokesman said the artillery was being fired on Kurdish forces protecting the city, and was a threat to U.S. personnel there.

The Pentagon said the military conducted the strike at 6:45 a.m. ET, against terrorists with the Islamic State.

Two F-18 aircraft dropped "500-pound laser-guided bombs on a mobile artillery piece," the Pentagon said.

On Thursday night, President Obama announced humanitarian aid would be dropped into stranded civilians in northern Iraq and said airstrikes would be used "if necessary" to protect U.S. personnel.

Fox News military analyst Gen. Jack Keane (Ret.) (video below) reacted this morning on America's Newsroom, saying he doesn't believe there is any long-term plan to defeat ISIS. He said U.S. officials know what banks ISIS uses and who manages their money, but the administration has not taken action on that front.

He criticized the president for, in June, refusing to take military action without political reconciliation among Iraqi leaders.

"That was an excuse not to act. The harsh reality is ISIS needs to be stopped regardless of the political situation in Iraq. Obviously it's important, but it's not primary. What is primary is stopping ISIS," said Keane.
