Migrants are arriving in Austria after Hungary's surprise move to provide buses for them.

For days, Hungary had blocked migrants from travelling by train to western Europe, saying it was obliged to register them, sparking angry scenes.

Austria says it has agreed with Germany to let the arrivals cross their borders.

European Union states are struggling to agree on how to deal with an unprecedented surge in migrants.

Buses began arriving at Keleti station, central Budapest, late on Friday, which for days has become a makeshift camp for thousands of migrants.

Transport has also been sent to the main road towards Austria, where hundreds have been walking along from the train station.

The BBC's Matthew Price, who has been travelling with the group, says there were fears among the migrants they would be arrested rather than sent to the border.

Another of our correspondents, Bethany Bell, saw a group of about 30 people walk across the Austria-Hungary border in the early hours of Saturday.

Many of the migrants hope to travel to Germany, which has said it expects to take in 800,000 people this year.

The Hungarian government said it had despatched the buses so that the country's transport network would not become "paralysed".

Austria's Chancellor Werner Faymann said that after talks with his German counterpart Angela Merkel, the two countries would allow in the migrants due to the "emergency situation" on Hungary's borders.

But he said he expected Hungary to respect any EU quotas for asylum seekers - something Hungary, along with the Czech Republic, Poland and Slovakia, has rejected.

Hungary has become a major transit nation for people fleeing the Middle East and Africa, seeking to reach north and west Europe.
