Serbian state television says police have stopped more than 100 migrants who tried to walk to Croatia from a refugee center in a Serbian border town. Police say a fire has damaged a former hotel that was being converted into a refugee home in eastern Germany and two people have been detained after hindering firefighters' work. Police said no one was injured, but a group of people gathered outside, some of them "commenting with derogatory remarks or unashamed joy" on the fire. The fire came three days after an incident elsewhere in Saxony in which a mob screaming "Go home!" blocked a bus carrying asylum-seekers outside a refugee home. Greek police say Macedonia has closed its southern border with Greece to Afghan migrants, allowing entry only for Iraqis and Syrians. Macedonian police started restricting the flow of migrants across the Greek-Macedonian border Saturday, conducting body searches and demanding passports.
