PHOTOS: 39 Killed, 69 Injured as Santa Claus Dressed Gunmen Attack Istanbul Nightclub

According to reports, the gunman, wearing a Santa Claus costume, killed a police officer and a civilian before he entered the club and opened fire at the people who were celebrating the New Year in Reina nightclub in the early hours of Sunday.

21 of the victims have been identified, of whom 16 are foreign nationals and five are Turks.
