Hungary

Found Thursday on the main Austrian highway leading to Hungary, the truck containing the victims' corpses was towed to a cooled border warehouse before police and forensic experts began the grisly work of unloading the partially decomposed bodies before shipping them to a Vienna morgue for autopsies.

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."

The ministry said Ildiko Vida's term of office ended Monday. It praised her work but said a new, more "client friendly" era is starting at the tax office.

Vida was one of six Hungarians banned from entering the U.S. because of suspected links to corruption. The U.S. government never named those people but Vida made public in November that she and colleagues from the tax office were on the list. She denied any wrongdoing.

Defense Minister Csaba Hende said 900 people will be working to install the 4-meter (13 foot) high fence along the 175-kilometer (109-mile) border.

"The Hungarian defense force is ready to complete this task," Hende said near the southern town of Morahalom.

In an open letter to Hungarian lawmakers, the UNHCR regional representative in Central Europe, said that while every country had the right to defend its borders and protect its citizens, the planned amendments "would make it impossible for people fleeing persecution to access international protection in Hungary."

Austria, meanwhile, reacted angrily to Hungary's announcement that, for an indefinite period, it would not take back refugees it registered when they entered Hungary but left for other destinations in Europe before their asylum requests were decided.

Foreign Minister Peter Szijjarto told reporters that several laws needed to be amended before construction of the fence could begin so he could not say exactly when the work on the "temporary border seal" could start.
