Nato joins fighter jets exercise
Nordic officials said Nato planes are joining their air forces in one of Europe's largest fighter jet exercises, as military tensions increase in the Nordic and Baltic region.
The two-week Arctic Challenge Exercise started today with more than 100 aircraft and 4,000 people participating. It follows Nato submarine detection drills off the Norwegian coast earlier this month.
The aerial manoeuvres, hosted by Nato-member Norway, include US F-16 fighter jets and military aircraft from Britain, Germany and France, accompanying non-Nato members Finland and Sweden.
Tensions have increased in the region since the Ukraine crisis.
Nato accuses Russian military aircraft of putting civilian flights at risk by boosting the number of its military air patrols and having its planes fly with their transponders switched off.
