| Since Hungary closed its border with Serbia and Croatia, Slovenia has become a bottleneck for thousands of migrants pouring through the region daily trying to go north into Europe |
Slovenia has threatened
to erect a fence along its border with Croatia if an EU plan agreed on Sunday
is not implemented.
Some
85,000 refugees have poured into the tiny nation in the last ten days, after Hungary
closed its Croatia border.
To
Hungary's north, Austria has also been beefing up barriers at its border
crossings to control large crowds.
The
approach of winter has so far done little to slow the flow.
The
UN estimates more than 700,000 migrants have crossed to Europe by boat so far
this year - mainly from war-ravaged Syria.
Most
have been making their way to northern Europe. Some transportation countries
have been seeking to limit the influx, leading to bottlenecks and tensions with
neighbors.
On
Tuesday, European Council President Donald Tusk warned that emergency could
create "tectonic changes in the European political landscape" - and
"not changes for the better".
