Fortress Europe: The millions spent on military-grade tech to deter refugees

Drones are being used to monitor the movement of refugees, but are largely ineffective in stopping people from crossing borders.

From military-grade drones to sensor systems and experimental technology, the EU and its members have spent hundreds of millions of euros over the past decade on technologies to track down and keep at bay the refugees on its borders.

Poland’s border with Belarus is becoming the latest frontline for this technology, with the country approving last month a €350m wall with advanced cameras and motion sensors.
