Serbian authorities say that a group of migrants and asylum-seekers who set off two days ago on a protest march toward the border with Hungary have traveled part of the route by train before proceeding on foot to seek entry into the European Union.

Ivan Miskovic from the Serbian government refugee agency says the group of several dozen people arrived by train early on Sunday in the northern town of Subotica and resumed walking from there. Subotica is about 10 kilometers (6 miles) from the border.

Some 300 young men and boys started marching Friday from Belgrade toward the Hungarian border, 200 kilometers (120 miles) away, to protest Hungary's decision to keep its border closed for most asylum-seekers, which has left several thousand stranded in Serbia.
