In 2015, Member States reported more than 1 820 000 detections of illegal border- crossing along the external borders. This never-before-seen figure was more than six times the number of detections reported in 2014, which was itself an unprecedented year, with record monthly averages observed since April 2014. The year 2015 began with extremely high levels for the month of January (over 20 000 detections, against the 2009–2014 January average of 4 700 detections), and each subsequent month set a new monthly record. In July, a turning point was reached with more than 100 000 detections,... coinciding with a change in the law in the former Yugoslav Republic of Macedonia allowing migrants to legalise their stay for a 72-hour period after they express a wish to apply for international protection. It resulted in a further increase of the flow and throughout the summer months scenes of chaos from the border areas spoke of a situation that appeared out of control. In September, public bus and train services were requisitioned in Western Balkan countries and in some Member States to transport migrants, but the flow continued to grow until October. As of November, the situation eased a little, but the EU’s total for December, at over 220 000 detections, was still way above the figure for the entire 2013.
