The latest developments as European governments rush to cope with the huge number of people moving across Europe. All times local (CET):

Thousands of migrants, many lacking food and water, remain trapped in southeast Europe after countries began putting up barriers that have blocked their passage to Western Europe.

On Saturday, Hungarian authorities were escorting hundreds of people to the border with Austria after Croatia became overwhelmed and dumped them on Hungary's doorstep the day before.

It wasn't yet clear how Austria would react to the large influx of people fleeing conflict and poverty in the Middle East and Africa.

In Slovenia, hundreds of people camped out overnight in Obrezje, a town just across the border from Croatia. Authorities only allowed limited numbers of families with women and children to continue on. Many migrants put up tents while others tried their best to keep warm as the temperatures dipped overnight.
