EU Tests New Walls, Sound Barriers To Keep Migrants Out

The European Union is intensifying its border security efforts to prevent migrant entry, particularly from Turkey. This includes deploying advanced technologies like sound cannons and observation towers. The EU has invested nearly $4 billion in these technologies since the 2015-2016 refugee crisis.
