An ISIS-associated YouTube account posted a new video online Tuesday entitled, “Weapons and munitions dropped by American planes and landed in the areas controlled by the Islamic State in Kobani.” The video was also posted on the Twitter account of “a3maq news,” which acts as an unofficial media arm of ISIS. The outfit has previously posted videos of ISIS fighters firing American made Howitzer cannons and seizing marijuana fields in Syria.

ISIS had broadly advertised its acquisition of a broad range of U.S.-made weapons during its rampage across Iraq. ISIS videos have showed its fighters driving U.S. tanks, MRAPs, Humvees. There are unconfirmed reports ISIS has stolen three fighter planes from Iraqi bases it conquered.

The authenticity of this latest video could not be independently confirmed, but the ISIS fighters in the video are in possession of a rich bounty of American hand grenades, rounds for small rockets, and other supplies that they will surely turn around and use on the Kurdish forces they are fighting in and around the Turkish border city.
