Media reports based on eyewitness and opposition sources saying that Turkey has become a party to the civil war in Syria have found their way into court proceedings. During the trial of the Islamic State (IS) militants who attacked Turkish security forces at Nigde last year, court files revealed that Turkey, beyond supplying opposition forces with weapons and ammunition, had also given artillery support to the opposition groups that captured Kassab. The prosecutor obtained striking admissions by tapping the defendants’ phones. According to documents obtained by Ahmet Sik of Cumhuriyet, the wiretapping transcripts reveal that the opposition forces at Kassab inform people in Turkey of the coordinates of Syrian army positions around Kassab, and then Turkey shells those locations.
On March 21, armed Syrian opposition groups entered Turkey from five different crossings and re-entered Syria at the Yayladag border crossing and captured Kassab.
