A senior Iranian official Thursday rejected the idea of a Syria **-fly zone, which Turkey wants, saying it would be "a mistake" and would **t restore security to the region. "Talk of the establishment of a buffer and **-fly zone is the repetition of previous mistakes and will **t help with security and stability in the region," deputy foreign minister Hossein Amir-Abdollahian said. Before it will join a US-led coalition staging air strikes on Islamic State group jihadists, Ankara wants an air exclusion zone and also a buffer zone along its border with Syria.
