“This kind of an incident, which may happen, as you expressed, of course, will further push us to take measures which of course are not discussed, simply are taken,” said Erdogan in an interview with CNN.

“These are things you simply make and do. And of course it would be an aggression against our rights of sovereignty and it’s the natural right of the state to protect those rights,” the Turkish president said.

“We do not want to see any escalation of the situation in the region,” he added. “We do not want to become a party to that. But those who side with Syria and escalate the tension, I think, are the responsible parties to this.”

According to Erdogan, in this case Turkey will be forced to "take measures that will certainly not be discussed."
