In Turkey, police have launched a series of raids across Istanbul, arresting at least 12 people, as police continue to search for a man who opened fire inside a nightclub during a New Year’s celebration, killing 39 people. ISIS has claimed responsibility for Sunday’s attack on the Reina nightclub, where hundreds of Turks and foreigners were celebrating early in the morning. The attack killed 11 Turkish citizens and more than two dozen tourists from Saudi Arabia, Iraq, Lebanon, Jordan, India, Morocco and other countries. This is a man who was inside the nightclub during the attack.

Younis Tuerq: “Actually, I didn’t see him. As soon as he entered the club, he started firing, and he didn’t stop. He fired nonstop for 20 minutes at least. We thought that there were several of them because it just didn’t stop. And there was some kind of bomb, as well; he threw some explosives. We managed to hide ourselves, and, luckily, he didn’t go out on the terrace. He stayed inside. He didn’t go out on the terrace.”

On Monday, Turkish authorities released two photographs of the suspected gunman. Officials say the Turkish military also attacked ISIS targets in Syria on Monday, killing at least 22 people. We’ll go to Istanbul and Washington, D.C., for more on the attacks after headlines.
