NATO is deploying eyes in the sky and on the Baltic Sea to protect cables and pipelines that stitch together the nine countries with shores on Baltic waters.

After a series of suspected undersea cable cuttings, NATO has launched a new surveillance and deterrence mission to protect critical infrastructure under the Baltic Sea.

Nato has launched a new mission to increase the surveillance of ships in the Baltic Sea after critical undersea cables were damaged or severed last year. Nato chief Mark Rutte said the mission, dubbed "Baltic Sentry", would involve more patrol aircraft, warships and drones.
