Former Russian President Dmitry Medvedev warned NATO on Tuesday against providing Ukraine with Patriot missile defence systems, denouncing the alliance as a "criminal entity" for delivering arms to what he called "extremist regimes".
Medvedev, who once cast himself as a liberal moderniser as president from 2008 to 2012, has increasingly emerged as one of the most hawkish proponents of Russia's war in Ukraine, posting scathing denunciations of the West on his social media channels.
