39 people were killed and at least 40 were wounded when two gunmen opened fire in a nightclub in Istanbul during New Year’s Eve celebrations on Saturday night.
Footage from the area appeared to show a number of ambulances and police vehicles outside the Reina nightclub, located in the Besiktas area of the city.
CNN Turk reported the two attackers were dressed in Santa costumes.
One local report said one of the attackers was still inside the nightclub and that special forces were preparing an operation to enter the building.
The attack comes three weeks after two explosions outside a soccer stadium in Istanbul killed 29 people and wounded 166.
In July, an attack on the Ataturk Airport in Istanbul left 45 people dead, including 19 foreigners.
Countries around the world were on heightened alert during New Year’s Eve celebrations on Saturday due to terror threats.
