Authorities also believe that the gunman, who killed 39 people, most of them foreigners, comes from a Central Asian nation and is likely to be either from Uzbekistan or Kyrgyzstan, the pro-government Karar and the mainstream Hurriyet newspapers reported, citing unnamed security sources. Police had also established similarities with the high-casualty suicide bomb and gun attack at Istanbul’s Ataturk Airport in June and was investigating whether the same IS cell could have carried out both attacks, the papers reported.
