BAGHDAD -- Militants with the Islamic State group on Wednesday shot down an Iraqi military attack helicopter, killing the two pilots on board in the second such incident in a week and raising concerns about the extremists' ability to attack aircraft amid ongoing U.S.-led airstrikes.
According to two Iraqi officials, the militants used a shoulder-fired missile to take down the Bell 407 helicopter, which crashed just north of the refinery town of Beiji, located about 200 kilometres north of Baghdad.
The pilot and co-pilot were both killed in the attack, a military aviation official told The Associated Press. A Defence Ministry official confirmed the information. Both officials spoke on condition of anonymity in line with regulations.
This is the second Iraqi military helicopter shot down by the Islamic State group over Beiji in one week. Militants shot down an Mi-35 helicopter near Beiji on Friday, also killing the pilot and co-pilot.
The two incidents highlight the Islamic State group's ability to counter air operations, potentially putting at risk U.S.-led airstrikes in Iraq and Syria. Some fear the militants may have captured ground-to-air missiles capable of shooting down airplanes when they overran Iraqi and Syrian army bases this summer.
European airlines including Virgin Atlantic, KLM and Air France, U.S. carrier Delta Air Lines and Dubai-based Emirates changed their commercial flight plans over the summer to avoid Iraqi airspace.
Also on Wednesday, a car bomb went off near a cafe in the sprawling Shiite neighbourhood of Sadr City in Baghdad, killing 10 people and wounding 25, according to police and hospital officials.
The officials spoke on condition of anonymity because they were not authorized to brief reporters.
