Nato is ramping up its military response after Russia launched an invasion of Ukraine, saying it had activated defence plans and would boost the alliance’s “deterrence and defence” by beefing up land, sea and air forces on its eastern flank and putting more than 100 warplanes on high alert.
Russian forces invaded Ukraine by land, air and sea on Thursday, confirming the worst fears of the West with the biggest attack by one state against another in Europe since World War Two.
