More than 100 Germans traveled to Ukraine to join pro-Russian separatist groups, German weekly Welt am Sonntag reported. According to the report, most of these foreign fighters were members of the ethnic Russian-speaking German families who were repatriated after the World War II. Welt am Sonntag quoted Ukrainian Ambassador to Germany as saying the Kiev administration has recently conveyed its concern to the German authorities. Melnik said that Kiev expects Germany to prevent the foreign fighters from flocking into Ukraine. Stephan Meyer, lawmaker from Chancellor Angela Merkel's ruling Christian Democrat bloc said that "If Germans take part in fights in conflict areas and they should face prosecution for terrorist activities." He also said that Germany should revoke the German passports of those foreign fighters who hold both Russian and German citizenships.
