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.

The blaze at the roof of the building in Bautzen, in the eastern state of Saxony, broke out early Sunday for reasons that remain unclear. 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. Police drew criticism in that case for hauling some migrants off the bus, which they insist was necessary to prevent the situation from escalating.

Greek police say Macedonia has closed its southern border with Greece to Afghan migrants, allowing entry only for Iraqis and Syrians.

Macedonian authorities reportedly said that Serbia has done the same on its southern border with Macedonia.

Macedonian police started restricting the flow of migrants across the Greek-Macedonian border Saturday, conducting body searches and demanding passports. Earlier, they had accepted Greek police's official documents attesting that an individual had been processed.

The moves have led to a buildup of migrants waiting at the Greek side of the border. Greek police said 800 were stranded at the border Sunday and another 2,750 were waiting in 55 buses nearby.

In the 24 hours to 6 a.m. local (0400 GMT) Sunday, only 310 migrants had been allowed into Macedonia.
