With Turkish security cooperating with its Israeli counterparts, Iran's relations with Turkey are taking a spin for the worst.

Turkish intelligence led by Khan Fidan is making a supreme effort, according to President Erdogan's directive, to locate Iranian intelligence cells in Turkey. 

President Erdogan fears possible harm to foreign tourism in his country. If Israeli tourists are harmed by terrorists, this will adversely affect the Turkish economy and he is determined to show that his country is safe.
