As reported here last year in both July and August, Turkey continues supporting ISIS. See the following posts for more information:
Islamic State militants are frequently transported across the Syrian border to Turkish hospitals for treatment, according to eyewitness accounts collected by RT on the ground. Their crossing was allegedly ensured by Turkish officials.
Both Islamic State (IS, previously ISIS/ISIL) and Free Syrian Army fighters were able to cross the border from Syria into Turkey en masse and receive medical help – only to then be allowed to go back to resume fighting in Syria, the head of a local doctors’ association told RT’s Lizzie Phelan.
Phelan visited Gaziantep, a city in south-central Turkey some 60 kilometers from the Syrian border. Eyewitnesses and doctors told the RT correspondent that most of the IS fighters were treated in the border city of Kilis south of Gaziantep.
