Turkish President Tayyip Erdogan accused US counterpart Barack Obama of going behind his back for criticising Turkey's press freedom record and linked it to efforts to "divide” Turkey, media reports said yesterday.

Obama said on Friday after meeting Erdogan on the sidelines of a nuclear summit in Washington that he was troubled by curbs on the press in Turkey and said he had urged Erdogan not to repress democratic debate in his country.

Turkey has drawn international condemnation for charging two journalists with treason for publishing footage that purportedly showed the intelligence agency shipping truckloads of weapons to opposition fighters in Syria in early 2014.

"I was saddened to hear that statement made behind my back. During my talk with Obama, those issues did not come up," Erdogan told reporters, according to Hurriyet daily. He returned to Turkey after a five-day trip to Washington yesterday.

Turkey has seized control of opposition newspapers and TV channels and cut the satellite feed of a pro-Kurdish channel, accusing them of terrorism-related activities. Erdogan has personally brought more than 1,800 criminal suits against individuals, including journalists and children, for insulting him.
