On Monday, some 27 bundles containing small arms, ammunition, and other weaponry were airdropped by the United States to Syrian Kurdish fighters defending the town of Kobane from IS.
Although a Pentagon spokesman confirmed that the majority reached the intended recipient, one bundle went astray but ‘was destroyed to prevent it from falling into enemy’s hands’.
However, a video uploaded to the internet by a media group loyal to IS showed a cache of weapons in militant hands. Activists from the Syrian Observatory for Human Rights confirmed that militants seized one cache.
Rear Adm Kirby said: "They are certainly of the kinds of material that was dropped... so it's not out of the realm of the possible in that regard.”
"When we have something definitive that we can provide in terms of an assessment on that we'll do that," he said.
IS is thought to be responsible for a series of bombings in Baghdad over the past few days which left dozens of people dead.
