Migrants stream into Austria, swept west by overwhelmed Hungary

"IT IS VICTORY"

Even as the buses arrived to collect them, some migrants remained suspicious, mindful of how hundreds of their number had boarded a train on Thursday that they believed was heading to the border but was stopped just west of Budapest by riot police who ordered them into a reception camp.

"They told us that the buses are going to the Austria border," said Ahmed, from Afghanistan. "I really don't know if this is true or false. If it is true, it is great... If it is true, it is victory. Maybe we can find a way now."

For days, Hungary has cancelled all trains going west to Austria and Germany, saying it is obliged under EU rules to register all asylum seekers, who should remain there until their requests are processed. Many have refused and several thousand had camped outside the Budapest train station.
