Several hundred refugees gathered at Budapest's Eastern (Keleti) Railway Station on Sunday, demanding they be allowed to travel on to Germany, Hungarian television channel M1 reported.
The refugees chanted: "Germany, Germany..." in English and also demanded a United Nations presence. They illustrated their demand visually by giving Germany a "thumbs up" sign and Hungary a "thumbs down" one, Xinhua reported.
The demonstrators were protesting against Hungarian police, who prevented them from boarding trains leaving the country.
According to M1 television, police have increased their presence at the station and are preventing refugees from entering.
An on-scene interpreter said the refugees were furious about not being allowed to board trains, given that most had already purchased their tickets.
