Islamic State group behind Istanbul nightclub attack
The Islamic State group has claimed responsibilitiy for attack on a popular Istanbul nightclub during New Year's celebrations, according to media reports.
Authorities 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 were investigating whether the same IS cell could have carried out both attacks, the papers reported.
The gunman, who is still at large, killed a policeman and another man outside the Reina club in the early hours of 2017 before entering and firing at an estimated 600 people partying inside with an automatic rifle.
There was no immediate claim of responsibility.
Nearly two-thirds of the dead in the upscale club, which is frequented by local celebrities, were foreigners, Turkey's Anadolu Agency said. Many of them came from the Middle East.
The mass shooting followed more than 30 violent acts over the past year in Turkey, which is a member of the Nato alliance and a partner in the US-led coalition fighting against IS in Syria and Iraq.
The country endured multiple bombings in 2016, including three in Istanbul alone that authorities blamed on IS, a failed coup attempt in July and renewed conflict with Kurdish rebels in the South East.
IS claims to have cells in the country. Analysts think it was behind suicide bombings last January and March that targeted tourists on Istanbul's famous Istiklal Street as well as the attack at Ataturk Airport in June, which killed 45 people.
In December, IS released a video purportedly showing the killing of two Turkish soldiers and urged its supporters to "conquer" Istanbul.
Turkey's jets regularly bomb the group in the northern Syrian town of Al-Bab. Turkish authorities have not confirmed the authenticity of the video.
Prime Minister Binali Yildirim said the attacker left a gun at the club and escaped by "taking advantage of the chaos" that ensued.
Some customers reportedly jumped into the waters of the Bosporus to escape the attack.
