Ukraine: Captured Russian soldiers 'on special mission'

Ukraine has said Russian soldiers captured after crossing the border were on a "special mission," contradicting a Russian defence ministry source's claim that it was accidental, Reuters reported.

"This wasn't a mistake, but a special mission they were carrying out," Ukrainian military spokesman Andriy Lysenko said.
