Foreign Minister Mevlüt Çavuşoğlu said late Wednesday that one of the bombers that perpetrated the twin blasts in central Istanbul last week came from Syria a week before the incident.
"One of the PKK members came from Syria a week before the terror attack," he said.
Two bombs exploded in a terrorist attack in central Istanbul last Saturday, close to Vodafone Arena in Beşiktaş district. One of the explosions was due to a suicide bomber and the other was a car packed with explosives.
The attacks left 44 people dead and 155 wounded. 14 of the wounded are currently under intensive care.
A day later, the terror attacks were claimed by PKK's suicide team, the Kurdistan Freedom Hawks (TAK).In the north of the war-torn country, the PKK's Syrian branch PYD and its armed wing YPG established the so-called "cantons" on the Turkish border. Despite claiming to be two seperate organizations, both groups usually exchange arms and militants, also collaborating in terror attacks in Turkey.
