The BBC is reporting that:
A group of Russian soldiers captured in eastern Ukraine had crossed the border "by accident", Russian military sources are quoted as saying. Ukraine said 10 paratroopers had been captured and has released video interviews of some of the men. One is quoted as saying "this is not our war”.
Maybe not, say the Ukrainians. But neither was it an “accident.” As a military spokesman put it:
"This wasn't a mistake, but a special mission they were carrying out."
