Macedonian authorities have reopened their borders to asylum-seekers heading north to wealthier European countries, but are only letting in people whose stated final destination is Germany or Austria.

About 1,700 people had been stranded for up to two days in freezing temperatures at Greece's northern border with Macedonia. The crossing opened just before midday Thursday.

Greek police are now asking migrants to state on their ID papers which country they are heading for. In November, Macedonia and other Balkan countries imposed a first check on transient migrants, excluding all but Syrians, Iraqis and Afghans, whom they deem refugees and not economic migrants.

The new limitation follows an Austrian decision to only allow in migrants heading for Austria or Germany, which had a shook up migration patterns in the Balkans.
