Several hundred asylum-seekers are camping out at the Turkish border with Greece, hoping that a meeting in Brussels on Wednesday will produce an agreement to let them into the European Union.

An Associated Press reporter in the Turkish border city of Edirne says that migrants remain at a wrestling arena about 8 kilometers (5 miles) from the Greek border Tuesday.

Hundreds of migrants have made the trek to Edirne in the hope of being allowed to cross into neighboring Greece or Bulgaria and avoid the often-risky journey across the Aegean Sea. Many arrived last week but have been blocked from approaching the border by law enforcement. Hundreds more were stranded in Istanbul after bus companies refused to issue them tickets.

Although many have pledged to remain until the borders are opened, many have given up on a crossing and have been bused back to other cities in Turkey. (By Mehmet Guzel)

Scuffles have broken out between Croatian police and asylum-seekers after they were barred from entering a newly opened reception center meant to register those seeking sanctuary in Europe.

Troubles started at the camp Tuesday, when more migrants came to the gates than authorities could handle. Police in the Croatian village of Opatovac pushed people back from the front gate, asked them to sit down and to wait their turn.

Croatia set up a migrant reception operation to try to bring order to the unrelenting chaos that has gripped the country since Sept. 15, when Hungary closed its border with Serbia. That decision diverted waves of people fleeing conflict and poverty in the Middle East, Africa and Asia to Croatia.

Austrian Police say about 1,000 new arrivals are expected soon at the main border crossing point with Hungary, after nearly 10,000 migrants and refugees trekked into the country Monday.

Police spokesman Helmut Marban said Tuesday that most of Monday's arrivals at the Nickelsdorf crossing east of Vienna had already been brought to emergency shelters elsewhere in the country.

He said Hungary is bringing the 1,000 people expected Tuesday to its side of the border by train.

From there, the migrants usually walk into Austria.
