If Russian aggression in eastern Ukraine escalates the European Union may take measures in response in June, according to European Council President Donald Tusk.
“After the Minsk agreement was signed, I still hope and I think that you may say that violence, aggression, hostilities have subsided. We should make further diplomatic efforts, and I hope that in June we’ll be able, as was the case before, to be united in our responses to possible bad behavior by certain neighbors of Ukraine,” he said at a joint press conference with Ukrainian President Petro Poroshenko and European Commission President Jean-Claude Juncker in Kyiv on April 27.
