Turkish President Recep Tayyip Erdogan on Thursday denied Russian accusations that Ankara was collaborating with the Islamic State, saying his country's fight against the jihadists was "undisputed".

"Our country's stance against Daesh has been clear since the very beginning," Erdogan said, using another name for the ISIS group. "There is no question mark here. Nobody has the right to dispute our country's fight against Daesh or to incriminate us."
