Forensic officers (unseen) work inside the Reina night club, one of the Istanbul's most exclusive party spots, early on January 1, 2017 after at least one gunmen went on a shooting rampage during New Year's Eve celebrations. Thirty-nine people, including many foreigners, were killed when a gunman reportedly dressed as Santa Claus stormed an Istanbul nightclub as revellers were celebrating the New Year, the latest carnage to rock Turkey after a bloody 2016. / AFP / OZAN KOSE (Photo credit should read OZAN KOSE/AFP/Getty Images)
