BUDAPEST, Hungary (AP) — The latest developments as European governments rush to cope with the huge number of people moving across Europe. All times local (CET):

9:45 a.m.

First groups of migrants have started arriving in Croatia — a new entry point into the European Union after Hungary sealed off its border with Serbia with massive coils of barbed wire.

About 80 people crossed early on Wednesday after they were first bused to the Serbian border town of Sid, following an all-night ride from the southern border with Macedonia.

Dozens of police and aid workers waited for the migrants across the border in Croatia, where they are being registered. Local media say some migrants have sought to cross into Croatia through nearby fields to avoid registration.

Officials say three more buses are expected to arrive in Sid later in the morning.

Migrants have avoided Croatia in the past because they must still go into Hungary or Slovenia before reaching Austria or Germany.

9:05 a.m.

Austria has begun selective controls of vehicles at three main border crossings with Hungary as it tries to impose some order over the stream of refugees and other migrants from that country.

Police say the controls, in effect since early Wednesday, may be extended to 10 crossings, with vehicles being stopped selectively for checks of passports and other travel documents.

Interior Minister Johanna Mikl-Leitner has said that Syrians and others in danger in their home countries can continue to ask for asylum in Austria. She says they will also be free to travel on to Germany, as has been the case up to now.
