Baghdad: Daesh militants shot down an Iraqi military helicopter Saturday, officials said, killing the two pilots onboard and raising fresh concerns about the extremists’ ability to attack aircraft amid ongoing U.S.-led coalition airstrikes.

The attack happened in the Shiite holy city of Samarra, about 95 kilometers (60 miles) north of Baghdad. A senior Defense Ministry official told The Associated Press the Sunni militants used a shoulder-fired rocket launcher to shoot down the EC635 helicopter on the outskirts of the city.

An army official corroborated the information. Both spoke on condition of anonymity as they weren’t authorized to speak to journalists.

The EC635, built by Airbus Helicopters, is used for transportation, surveillance and combat.

The militants shot down at least two other Iraqi military helicopters near the city of Beiji in October. 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.

Anbar attack

In Anbar province, Daesh fighters stormed a town on Saturday, killing at least 19 policemen and trapping others inside their headquarters, in the latest attack in the desert region where it controls large amounts of territory, officials said.

They seized the town of Al Wafa, 45 km west of Anbar’s capital Ramadi on Saturday after starting its assault early on Friday.

With the capture of Al Wafa, Daesh now controls three major towns to the west of Ramadi, including Hit and Kubaisa. Islamic State and government forces have been bogged down in a months-long battle for Ramadi.
