Ten young refugees were rescued after the shelter in which they were staying in southern Germany caught fire Friday, authorities in the town of Ruppertshofen said. According to dpa, no injuries were reported among the rescued, all of whom are minors who have reached Germany without adult accompaniment. The cause of the fire remains unclear. The blaze was noticed by a shelter worker around 3:30 am (0230 GMT) and an alarm was sounded. The fire seems to have started in a nearby garage, but spread to the shelter. Parts of the shelter's attic were destroyed by the fire. Police have launched an investigation into the cause of the blaze. Firefighters were also called out to refugee accommodation in the outskirts of Hanover in the early hours of Thursday morning following an arson attack. There were no injuries among the 60 refugees living in the building, police said Friday.
