Ukraine crisis: Russian soldiers 'were ready to shoot'

Ukrainian air defence troops have attempted to regain control over Belbek airbase in Crimea, after it was seized by Russian military.

A Ukrainian major at the base has said he was shocked to see Russian soldiers "ready to shoot".

Major Vladyslav Kardash told BBC's Abdujalil Abdurasulov that it was "impossible" to believe that the Russian military could be an enemy.
