Poland has sent security forces to its border with Russia's Kaliningrad exclave after suspicious night-time activity.
Prime Minister Donald Tusk said people with flashlights were spotted near the border at night, and forces and equipment were dispatched quickly to the area. No further details on who the people were have been given.
The incident comes as NATO's eastern flank stays on edge over Russian activity, and even an unexplained night on the border now draws an immediate response.
