NATO is launching a new mission to protect undersea cables in the Baltic Sea region after a string of incidents that have heightened concerns about possible Russian activities, the alliance’s leader said.

NATO Secretary-General Mark Rutte announced on Tuesday a new mission, dubbed Baltic Sentry, to safeguard undersea cables in the Baltic Sea region.

NATO countries will deploy frigates, patrol aircraft and naval drones in the Baltic Sea to help protect critical infrastructure and reserve the right to take action against ships suspected of posing a security threat,
