In Hungary, police say 2,500 migrants are thought to have crossed the border from Serbia on Tuesday.
It means more pressure on the temporary holding camp at Roszke, where the situation is already tense.
“We came here last night. We tried to get across the border without being fingerprinted.” one man told reporters.
The area has become a bottleneck.
Nearby transit camps are struggling to cope with the demand.
Crowds of migrants are said to be gathering once more at Budapest’s main station, hoping to get a train to Germany.
