ISTANBUL // Turkish state media aired a “selfie” video on Tuesday of a man believed to be the gunman who killed 39 people at a nightclub in Istanbul. The camera never leaves the man’s unsmiling face as he walks through Taksim square – one of Istanbul’s prime tourist spots – during the 44-second video broadcast on state-run Anadolu television and other media. It wasn’t immediately clear if the video was filmed before or after the New Year’s massacre at the Reina nightclub, or how the footage was obtained. The gunman, who hasn’t been publicly identified, is still at large. ISIL claimed the attack on Monday, saying a “soldier of the caliphate” had carried out the mass shooting to avenge Turkish military operations against ISIL in northern Syria. At least 14 people have been detained in connection with the attack. Two foreigners were detained at Ataturk airport’s international terminal on Tuesday after police checked their mobile phones and luggage, according to Anadolu. A woman identified by Turkish media as the wife of the massacre suspect has told police she didn’t know her husband was an ISIL member, according to the Hurriyet newspaper. The woman was detained in the central town of Konya as part of the investigation. Neither she nor her husband has been identified by name. The woman said she learnt about the attack on television and told police she didn’t know her husband harboured “sympathies toward” ISIL, Hurriyet reported. Media reports say the gunman flew to Istanbul from Kyrgyzstan with his wife and children on November 20. From there, they drove to the Turkish capital, Ankara, before arriving in Konya on November 22. The family rented a studio in Konya, paying three months of rent upfront. The gunman told the estate agent he had arrived in Konya in search of work. Hurriyet said the gunman returned to Istanbul on December 29. Reports said police made progress in the investigation after speaking to the taxi driver who drove the attacker to the club and tracing calls he had made on the driver’s mobile phone. Hurriyet reported the attacker showed signs of being well trained in the use of arms and had fought with ISIL in Syria. Armed with a long-barrelled weapon, the gunman killed a policeman and a civilian in the early hours of 2017 outside the Reina club before opening fire on the estimated 600 people inside. Most of the dead were foreign tourists. Hurriyet’s well-connected columnist, Abdulkadir Selvi, said the gunman had been trained in street fighting in residential areas of Syria and used these techniques in the attack, shooting from the hip rather than as a sniper. The gunman had been “specially selected” to carry out the shooting, he said. According to newspaper, just 28 bullets failed to hit a target. On Monday, several media outlets – citing unnamed security sources – said the attacker was believed to be from Central Asia and may have been part of the cell that staged an attack on Istanbul’s Ataturk airport in June that killed 45 people. The Haber Turk newspaper reported on Tuesday that the man was thought to be a member of China’s Muslim Uighur minority. A Kyrgyz passport circulated on Turkish media but police said it did not belong to the gunman. Kyrgyzstan’s intelligence services said on Tuesday it was investigating whether one of its citizens was involved in the New Year’s attack. * Associated Press, Agence France-Presse
