Italy, Spain and Slovenia expelled a raft of Russian diplomats Tuesday amid increasing outrage over the Ukraine conflict, bringing to almost 200 the number ordered home by EU allies in 48 hours.After expulsions Monday by Germany and France, Sweden, Denmark and Estonia also followed suit Tuesday — while the European Union itself declared "persona non grata" a group of Russian officials working with EU institutions.The expulsions were for alleged spying or "national security reasons," but follow international condemnation of killings in the town of Bucha, near Kyiv, where dozens of bodies were discovered after Russian troops withdrew.Moscow has rejected Western accusations that its forces were responsible, suggesting the images are fake or the deaths occurred after they pulled out.Kremlin spokesman Dmitry Peskov told reporters Tuesday that the mass expulsions of its diplomats was "a short-sighted move.""Narrowing down opportunities for diplomatic communication in such an unprecedentedly difficult crisis environment is a short-sighted move that will further complicate our communication, which is necessary to find a solution," he said."And this will inevitably lead to retaliatory steps," he added. The expulsions come as the EU discusses a fifth round of sanctions on Russia for its invasion of Ukraine on Feb.
