Poland expels four Russian diplomats after UK nerve agent attack

Poland will expel four Russian diplomats as part of a wider European action to show unity with Britain over the poisoning of a former Russian spy in England that London has blamed on Moscow. Polish Foreign Minister Jacek Czaputowicz told a news conference that the diplomats were to leave the country by April 3. "Showing solidarity with Britain and other countries is the most important thing," Czaputowicz said. "There are diplomatic costs to that but they are worth it."
