At the Hungarian-Serbian border (CNN)Hungarian riot police used tear gas and water cannons Wednesday on migrants at the country's border with Serbia after a group broke through a barrier to try to enter the European Union.
Crowds of desperate migrants, most fleeing violence in the Middle East, were left stranded in Serbia after Hungary sealed the final hole in its border between the two countries Tuesday, closing a popular migration route to Western Europe.
At Horgos, Serbia, on the border with Hungary, CNN's Ben Wedeman said the standoff started when some migrants began demonstrating, saying they were giving Hungarian authorities two hours to open the gate before they attempted to break through.
When the group followed through on the threat, Hungarian security forces, who had brought in armored vehicles, responded with the tear gas and water cannons.
A running battle surged back and forth as the migrants waited for the tear gas to clear before rushing the border fence again, throwing bottles and rocks at the Hungarian forces.
One man insisted he and his fellow migrants would not go back -- that they were determined to cross the border into Hungary.
