The US Defense Department is investigating video footage appearing to show Islamic State fanatics with at least one cache of weapons airdropped by coalition forces that was meant for Kurdish militiamen battling the extremist group in a border town. The cache of weapons included hand grenades, ammunition and rocket-propelled grenade launchers, according to a video uploaded by a media group loyal to the Islamic State (ISIS) group. The video appeared authentic and corresponded to The Associated Press' reporting of the event. At one point a fighter in the video says: 'Thanks be to God! Spoils and booty for the mujahideen.'

While
Kurdish are battling on the ground, a U.S.-led coalition is also targeting the militants from the air.
