Dutch security services are preparing for terrorist attacks that may use drones.
Drones could potentially be used to carry bombs, toxic gases or biological weapons that could then be dropped onto people or buildings.
To prevent attacks by drones the police and the National Coordinator for Counterterrorism (NCTb) are training eagles that can pluck them out of the air.
They are working with a company called Guard from Above, which is a raptor training firm in Denmark.
The eagles are able to instinctively grab the offending drones out of the sky and automatically take them to a safe area away from people. The eagle handlers then trade the drones for a treat that the eagles can eat.
