At the Hungarian-Serbian border (CNN)A day after Hungarian riot police used tear gas and water cannons to turn back people at the country's border with Serbia, migrants attempting to reach Western Europe were left with a difficult choice: Stay and contend with Hungary's tough new border defenses, or set out through Croatia on another uncertain path toward the European Union's wealthier nations.
Frustrations boiled over Wednesday afternoon after Hungary had sealed the final hole in its border with Serbia a day earlier, shutting off a popular route used by tens of thousands of people in Europe's vast migrant crisis.
The move left desperate men, women and children -- most of them fleeing violence in the Middle East -- blocked by a razor-wire fence from entering Hungary.
