The UN Security Council on Friday strongly condemned the deadly bombing that killed 16 people in Vladikavkaz, a major Russian city in the Caucasus, dpa reported.
The 15-nation council issued a statement expressing "deep sympathy and condolences to the victims of the heinous act of terrorism and to the families, people and government of Russia."
The council said acts of terrorism in all its forms and manifestations are serious threats to international peace and security. It said those acts are "criminal and unjustifiable."
The attack on Thursday targeted the centre of the city as Moscow was fighting Islamist insurgents in northern Caucasus. No group has claimed responsibility for the attack.
