The United Nations, looking to modernize its peacekeeping operations, is planning for the first time to deploy a fleet of its own surveillance drones in missions in Central and West Africa.

The U.N. Department of Peacekeeping has notified Rwanda, Uganda and the Democratic Republic of the Congo that it intends to deploy a unit of at least three unarmed surveillance drones in the eastern region of Congo.

The action is the first step in a broader bid to integrate unmanned aerial surveillance systems, which have become a standard feature of Western military operations, into the United Nations' far-flung peacekeeping empire.
