STRASBOURG (Reuters) - European Union chief executive Jean-Claude Juncker appealed to European countries on Wednesday to share out a wave of refugees crowding in on their frontiers, but at the same time promised tougher border controls to keep unwanted migrants out.

As he spoke, disarray across the continent was driven home when police in Hungary, Austria and Denmark closed major highways as groups of migrants, hundreds strong, marched north. Defying Hungary's new border fence and EU asylum rules, tens of thousands are crossing frontiers to reach Germany and Sweden.
