LJUBLJANA, Slovenia/BERKASOVO,Serbia (Reuters) - About 3,500 migrants spent the night camped out in freezing cold at the Berkasovo-Bapska border crossing between Serbia and Croatia after the Croatian government closed the gates to limit the number of people entering the country.

At first light on Thursday, groups of refugees bypassed the official border crossing and walked through orchards into Croatia.
