The Baghdad FIR roughly follows the Iraqi border
The European EASA issued an amended warning on Iraqi airspace.
On April 13, EASA issued Conflict Zone Information Bulletin CZIB 2017-04R2. The risk is described as:
Due to the presence of various weaponry including MANPADS (man-portable air-defence systems), it is advised to be cautious with the risk associated to civil aviation. The risk to operations at all altitudes is assessed to be HIGH, except for airways UM688 and UM860. The highest airspace risk is estimated to be along the entire Iraq/Syrian border.
The validity is extended until 13 October 2018.
