Czech police removed about 200 migrants from trains heading towards Germany and tagged them with numbers, local media reported on Wednesday.
The newspaper 'Zpravy' said the refugees had arrived from Budapest and were then placed in detention centers after they were removed from the train in the eastern province of Moravia. The majority of the refugees had reportedly come from Syria.
Michal Hasek, governor of southern Moravia where the train was stopped, said that authorities in the region "were preparing for what would occur if the wave of refugees increased."
Italian Jews outraged about Czech police action
Italy's Jewish community protested against the Czech police's actions, saying it was inconceivable that 70 years after the Shoah people in Europe were being marked like cattle.
Several Jewish communities in Italy have opened centers in recent weeks to help incoming refugees.
Budapest's main railway station shut down temporarily
Meanwhile, hundreds of migrants demanding to travel to Germany faced off with police outside Budapest's main railway station late Tuesday, as new figures highlighted the unprecedented scale of Europe's refugee crisis.
More than 350,000 people, many from war-torn Syria, have made the perilous crossing of the Mediterranean so far this year, the International Organization for Migration (IOM) said.
Police cleared and briefly shut Budapest's Keleti station a day after thousands of migrants boarded trains for Germany and Austria. As night fell, around 500 mainly Syrian migrants, still blocked from the station entrance by a police line, chanted "Germany! Germany! Hungary, let us go!".
The police continued to hold back, though, and by midnight the tension had eased, with most of the migrants retreating to a nearby makeshift refugee shelter to sleep, many vowing to return to the station entrance in the morning. "What else can I do," Ahmad Orabi, a 25 year-old Syrian from Homs, told AFP. "I've come so far, I can't give up now."
Hungarian railway authorities said earlier they would allow "only those in possession of the appropriate travel documents and -- if necessary -- a visa" to board trains travelling to western Europe.
