The Sunday Times reports that Germany, Austria, Belgium, Sweden and Denmark are set to  warn Greece that it has six weeks to curb its migrant flow or else it will be “quarantined” outside the EU’s borderless Schengen area.

Northern EU countries are frustrated that Greece has opened one in five refugee processing and detention centers it had pledged to set up and are mulling their next moves that could indeed lead to a temporary Schengen zone exit.
