BAD REICHENHALL, GERMANY - SEPTEMBER 14: A German police officer holds a stop sign as he observes traffic entering Germany at the border to Austria on September 14, 2015 near Bad Reichenhall, Germany. German authorities announced they are temporarily reinstating border controls along Germany's border to Austria in order to stem the recent massive influx of migrants and uphold the Dublin agreement. Tens of thousands of migrants arrived in Germany over the last few weeks and the country is struggling to find adequate accommodation for them all. By enforcing the Dublin agreement, which requires migrants applying for asylum to register in the first EU country they enter, German authorities are hoping for a broader distribution of arriving migrants across EU member states.
