Hundreds of migrants have set off on foot toward Serbia's border with Hungary to protest Hungary's decision to keep its border closed for most people trying to reach the European Union after fleeing war and poverty.

Migrants held makeshift banners reading "Hungary Open Borders" or "No Borders, No Fence" as they marched Friday in a long column along a road leading north from Belgrade. Several police cars drove slowly by the marchers. Most migrants appeared to be young men who stand little chance of entering Hungary or other EU nations.

Hungary has recently strengthened anti-migrant controls on its southern border with Serbia, letting in only about 30 people a day, mostly families with small children.

Many migrants have turned to human smugglers to help them cross the border.
