In November 2015, there were talks inside the governing coalition to stop family unification for migrants for two years, and to establish "Transit Zones" on the border and – for migrants with low chances to get asylum approved – to be housed there until their application is approved. The issues are in conflict between the CSU who favoured those new measures and threatened to leave the coalition without them, and the SPD who opposes them; Merkel agreed to the measures. The November 2015 Paris attacks prompted a reevaluation of German officials' stance on the EU's policy toward migrants. There appeared to be a consensus among officials, with the exception of Merkel, that a higher level of scrutiny was needed in vetting migrants with respect to their mission in Germany. However, while not officially limiting the influx numerically, Merkel tightened asylum policy in Germany.
