The 2013 bombings claimed lives of over 50 people, while more than 150 were injured, according to media reports. Ankara put the blame for the attack on Damascus. Syria refuted the claims.
Ankara managed to capture the suspect, 34-year-old Turkish citizen Yusuf Nazik, in the Syrian port city of Latakia. The detainee claims that he was acting on the orders of the Syrian intelligence, local media said.
