The over-flow of refugees being sent back to Turkey for re-assessment before being allowed into Europe. It’s unfortunate but some European countries have not played their part and consequently there are too many refugees to be accommodated. European countries need time to assimilate the refugees they already have before receiving more. Hopefully the arrangements in place now will stem the tide of refugees before they go any further and allow authorities in Germany and other countries with refugees, to move them into communities, and consequently free-up short-term accommodation for new arrivals.
Some right wing political groups in receiving countries are resisting the arrival ofl refugees for particular reasons, thereby adding to the problem.
