NATO planes police air over Baltics NATO military planes take part in a training mission over Lithuania as part of the Baltic air-policing mission based in Siauliai. The US-led military alliance have deployed more aircraft, ships and personnel, aiming to reassure newer members such as the Baltic states and Poland, once ruled from Moscow, who have been unnerved by Russia's intervention in Ukraine. Last year NATO intercepted Russian aircraft on more than 100 occasions, a threefold increase on the previous year. IMAGES
