The spokesman for Operation Inherent Resolve, Colonel Wayne Marotto, said in a tweet, "the International Coalition for Operation Inherent Resolve has not conducted airstrikes in Syria or Iraq today or yesterday. The U.S./Coalition has the inherent right to self-defense. Force protection remains the highest priority of the Coalition."

The Imam Ali brigades, which is affiliated with al-Hashd al-Shaabi, said that the explosions that rocked one of its ammunition depots were caused by two airstrikes launched by an unidentified drone.

 The division said in a statement that a drone bombed one of the ammunition depots in Al-Duyouk camp at 3:30 pm, before it re-targeted the same camp at 5:30 pm.

However, the Security Media Cell denied these claims and said in a statement that the Joint Operations Command formed an investigative committee to find out the causes of the explosion.
