Migrants queue in the compound outside the Berlin Office of Health and Social Affairs (LAGESO) as they wait to register in Berlin, Germany, October 12, 2015. More than a million refugees will come to Germany this year, Chancellor Angela Merkel's deputy said on Sunday, as a poll showed almost half of Germans believe she is handling the influx of asylum seekers badly. German authorities are struggling to cope with the roughly 10,000 asylum seekers arriving every day. The German government still officially expects 800,000 asylum applications in 2015, while media say up to 1.5 million people could come. REUTERS/Hannibal Hanschke TPX IMAGES OF THE DAY
