According to the Doğan News Agency and Hürriyet Daily News, Turkey’s military has deployed teams trained to deal with chemical weapons attacks to the Syrian border. This follows a warning by Damascus that it may use these weapons in the event of an attack from outside the country. The chemical weapons battalion, previously based in western Turkey, was transferred to Konya in central Turkey two months ago. One group of personnel has now been moved to the Syrian border.
Ankara is particularly concerned by the situation in Qamishli, a town on Turkish border adjoining Nusaybin, because the PYD is concentrated there. There have been reports that the PYD is preparing to take control of the town from the Syrian administration as it has in Kobane, Efrine, and Amude in the city of al-Hasakah.
