Frustrations boiled over Wednesday afternoon after Hungary had sealed the final hole in its border between the two countries a day earlier, closing a popular migration route to Western Europe. The move left thousands of migrants, most fleeing violence in the Middle East, blocked from entering Hungary by a razor-wire fence.

After Hungary’s new migrant law came into effect on September 15 and border fence with Serbia was finished, the migrants blocked in the Hungary-Serbia border area will have to find other way to reach other EU country. Meanwhile, Germany has enhanced border check as it is trying to control the record influx of migrants into Germany.
