A United Nations panel assessing the future technological needs of peacekeeping missions has recommended dramatically expanding the use of unmanned surveillance drones in U.N. military operations, the head of the panel said on Monday.

Jane Holl Lute, who was previously U.S. deputy secretary for Homeland Security and a senior U.N. peacekeeping official, said that was one of 119 recommendations the expert panel on technology and innovation in U.N. peacekeeping made in a new report.

"We make a very strong recommendation that drones, or the capacity for aerial visualization, is a capacity every mission should have with very few exceptions," Lute, who led the expert panel, told reporters.
