NATO is preparing for nuclear drills and has doubled the number of warships in the Baltic Sea to 30 in a show of strength after the 'horrific' Russian bombing raids in Ukraine.
NATO Secretary-General Jens Stoltenberg told Moscow on Tuesday it would meet attacks on allies' critical infrastructure with a 'united and determined response' and was monitoring Russia's nuclear forces closely as the country was 'losing on the battlefield' in Ukraine.
Ahead of a two-day meeting of the Western alliance's defence ministers in Brussels, he added that it had not seen any changes in Russia's nuclear posture, but was 'vigilant'.
Stoltenberg described Russia's missile strikes on civilians in Ukraine on Monday as a sign of weakness.
