The EU has begun a crucial summit on the migrant crisis, but a rift has already emerged on the closure of the main route through the Balkans.

A draft communique had revealed the EU was about to declare the route "now closed", but the German government rejected this as "speculation".
Turkey is also attending the summit, which is tackling Europe's worst refugee crisis since World War Two.
The EU will press Turkey to take back migrants in return for $3.3bn in aid.
Last year, more than a million people entered the EU illegally by boat, mainly going from Turkey to Greece.
Many migrants leave Greece in a bid to reach northern Europe, but eight countries have introduced temporary border controls.
Some 13,000 migrants are currently stranded in northern Greece, after Macedonia, backed by Croatia, Hungary and Slovenia, closed its border to all but a trickle of migrants.
