Hungary

Police spokeswoman Viktoria Csiszer-Kovacs says Friday the four detained Thursday in Hungary include three Bulgarian citizens and one person from Afghanistan. One of the Bulgarians is the owner of the truck. Nearly 20 other people were questioned as witnesses and houses connected to the case were also searched.

 Then they jostled to formally enter the country so they could quickly leave it, heading toward more prosperous European Union nations on a desperate quest to escape war and poverty.

In Roszke, a Hungarian border town, migrants mostly from Syria, Iraq and Afghanistan requesting asylum were being processed by authorities. Police used tear gas to break up a brief scuffle involving about 200 migrants, saying the migrants were growing impatient with delays in the registration process caused by the growing number of arrivals.

According to police data, 2,093 migrants were detained Monday, the highest figure so far this year. Over the past week, the daily average was of 1,493 migrants.

The surge comes after nearly 10,000 people, including many women with babies and small children mostly from Syria, rushed across the Macedonian border into Serbia over the weekend.

Another 1,000 arrived in Serbia Tuesday morning and their next stop is most likely to be EU-member Hungary.

Prime Minister Aleksandar Vucic spoke as he talked to migrants from the Middle East, Africa and Asia who were camping Wednesday in a Belgrade park. He said Serbia has no plans to build fences on its border even though it is being overwhelmed by the flood of migrants.

Vucic says "we won't build those wires, those barbed wires. It only takes for someone to switch the electricity through those wires and to finish the job."

Government spokesman Zoltan Kovacs said that Interior Minister Sandor Pinter assured a Cabinet meeting that the deadline, which had earlier been set for Nov. 30, could be met.

According to Kovacs, Pinter said "that the security fence can be built along its full length in a month."
