Nato set for biggest military exercise in 13 years

Nato has unveiled details of its biggest military exercise in 13 years - mobilising 36,000 soldiers, sailors and airmen from more than 30 countries.

Officials said that the exercise, named Trident Juncture, has been planned for years, but is being tweaked to test Nato’s ability to respond to new security threats like those highlighted by Russia’s takeover of Crimea and the spread of radical groups like Islamic State in the Middle East and North Africa.
