Who killed 150 to 250 ISIS fighters and destroyed their vehicles near Fallujah?

It seems that the different players in the fight against ISIL are now competing for credit.

On Wednesday, Iraqi military released footage showing destroyed cars and trucks. Military officials claimed that the raid was carried out by Iraqi pilots who were using Russian made helicopters. It should be noted that it was reported that "Iraq has received their final batch of Russian Mi-28 NE Night Hunter military helicopters". The attack footage indicated that these helicopters were used. NBC News reported the same story.

Reuters, on the other hand, reported the following:

U.S.-led coalition aircraft waged a series of deadly strikes against Islamic State around the city of Falluja on Wednesday, U.S. officials told Reuters, with one citing a preliminary estimate of at least 250 suspected fighters killed and at least 40 vehicles destroyed.

Iraqi officials indicated that U.S. refused to assist with the attack they took credit for. These conflicting reports show that the U.S. led anti-ISIL coalition is not as unified behind the mission as they claim.

Video footage of the attack, one of the attacks, or something like that:

Meanwhile, more American weapons fell in the hands of ISIS when another so-called "moderate" Syrian rebel group attempted to push out ISIS from a town near the Iraqi border. According to reports, 40 of the rebel were killed and 15 taken prisoners by ISIS.

The Syrian Observatory for Human Rights said the group's offensive against ISIS was being mounted with the backing of Western special forces and US-led air strikes.
