Hundreds of migrants, many of them refugees from the Syrian war, woke after a night spent on a packed train stranded at a railway station west of Budapest, refusing to go to a nearby camp to process asylum seekers. The train had left Budapest on Thursday morning after a two-day standoff at the city's main railway station as police barred entry to some 2,000 migrants. REUTERS/Leonhard Foeger
