AACHEN, Germany (Reuters) - Germany needs to take action now to prevent a re-run of 2015, when some 890,000 migrants arrived in the country, Chancellor Angela Merkel's Social Democrat challenger for a September election told Reuters on Sunday.
In September 2015, Merkel threw open Germany's borders to thousands of migrants to avoid a humanitarian disaster - a move that later hit her popularity and boosted the anti-immigrant Alternative for Germany (AfD), though her conservatives have since recovered and support for the AfD has dropped.
