The Iraqi Government says Islamic State group militants have shot down an Iraqi army helicopter over Mosul, killing the two-member crew. The Ministry of Defense says in a statement that the incident happened during the operation to retake the city from IS militants. The chopper came down as a result of ground fire and landed somewhere in eastern Mosul. Footage from an AP cameraman shows a large ball of fire with a long trail of thick black smoke as the aircraft falling out of the sky Thursday afternoon.
