On Sunday, U.N. High Commissioner for Refugees Filippo Grandi warned of what he called a “climate of xenophobia” in Europe. His remarks came three days after Labour Party Parliament member Jo Cox was shot and killed by a constituent in Britain. The Southern Poverty Law Center said the shooter, Thomas Mair, is a longtime supporter of the neo-Nazi National Alliance and attended a 2000 meeting of British white supremacists. Todd Blodgett, a paid FBI informant, helped arrange the meeting in London. In court Friday, Mair gave his name as “Death to traitors, freedom for Britain.” Britain votes Thursday on whether to leave the European Union.
