Russian President Vladimir Putin's announcement of a partial mobilisation in Russia is a "worrying escalation," a Foreign Office minister has said.
Gillian Keegan also urged for calm in the face of Putin 's threat in his speech to use nuclear weapons.
Putin warned the West that Russia would use all the means at its disposal to protect its territory, saying: "It's not a bluff." He accused the West in engaging in "nuclear blackmail" and noted "statements of some high-ranking representatives of the leading Nato states about the possibility of using nuclear weapons of mass destruction against Russia".
