On October 18, the European Aviation Safety Agency (EASA) extended the validity of Conflict Zone Information Bulletin CZIB 2017-03R3 to 18 April 2019.
The risk is described as:
Due to the hazardous security situation, with the presence of terrorist organisations and ongoing high intensity military operations, there is a risk of both intentional targeting and misidentification of civil aircraft. The presence of a wide range of ground-to-ground and dedicated anti-aviation weaponry poses a HIGH risk to operations at all flight altitudes.
