Foreign ministers from four eastern European countries are preparing to meet in Prague to discuss the migrant influx amid continuing stark divisions.

The meeting becomes imperative as the influx through EU's southern borders keeps burgeoning.

Poland, Hungary, the Czech Republic and Slovakia remain strongly opposed to accepting obligatory quotas.

Germany and France want migrants shared out more evenly across the EU.

Thousands more migrants entered Austria over the weekend and more are expected to arrive via Hungary on Monday.

Croatia's authorities tweeted that 29,000had entered its territory by early Monday morning.

EU interior ministers are to meet on Tuesday, with leaders convening for an extraordinary summit the following day.

Divisions among European stateswere illustrated by French President Francois Hollande, who said that in the EU "no-one can be exempt" from taking in people with the right to asylum.

European Council President Donald Tusk said that the EU should help Syrian refugees to "a better life closer to their homes".

Eastern European countries are stressing the need to protect the EU's external borders and distinguish between economic migrants and refugees.
