Russia's President Vladimir Putin has vowed to "fiercely and consistently continue the fight against terrorists until their complete annihilation" following the twin suicide bomb attacks on the city of Volgograd.
Russia has called for international solidarity in the fight against "terrorists" after two deadly suicide bombings in the southern city of Volgograd.
In a statement, the Foreign Ministry said: "We will not retreat and will continue our consistent fight against an insidious enemy that can only be defeated together."
It did not place direct blame on any particular group for the attacks but said they came against a backdrop of threats from militants.
They include Doku Umarov, leader of an Islamist insurgency in the North Caucasus who has called on fighters to prevent Russia holding the Winter Olympics in February.
