Turkish officials said Wednesday that the suspected gunman in a New Year’s night attack on an Istanbul nightclub has been identified. Foreign Minister Mevlüt Çavuşoğlu announced the development in a TV interview, but he did not provide any other information about the suspect, who has not been publicly named. Officials on Tuesday released a video of the alleged shooter, but it was unclear how they had obtained the footage or connected it to the mass shooting. Several arrests have been made in connection to the massacre, but the search for the gunman continues. Thirty-nine people were killed in the club during the early morning hours of New Year’s Day, and dozens more were injured. ISIS has claimed responsibility for the atrocity.
