DHAKA: Tensions are building among thousands of migrants heading north through Balkan states as their route to Western Europe is stalled by new controls.

Croatia had asked its northern neighbour Slovenia to accept 5,000 migrants daily, but Slovenia said it would only take half that number, reports the BBC.

The move has led to a build-up of people on Croatia's border with Serbia.

An official said that Croatia could run out of room in its transit camps within days.

Buses crammed with people were backed up in Serbia on Sunday, and tempers flared between frustrated migrants and overstretched police officers.

Thousands of asylum seekers are travelling north through the Balkans, with most aiming to reach Austria, Germany and other EU states.
