Former Russian President Dmitry Medvedev said on Wednesday that an alleged missile strike on Polish territory showed that the West was moving closer to another World War.

“The incident with the Ukrainian-alleged ‘missile strike’ on a Polish farm proves just one thing: waging a hybrid war against Russia, the West moves closer to world war,” Medvedev wrote on Twitter.
