Footage released to Twitter by an unknown individual claiming to be a Russian shows the sabotage of a Russian KA-52 on the Pskov airfield.

While we're unable to independently verify that this footage does in fact show a Russian saboteur conducting an operation to destroy Russian aircraft at the Pskov airfield, reports out of Pskov do indeed confirm that two Ka-52 attack helicopters were destroyed in an unexplained explosion six hours ago.

For the geographically challenged, Pskov is 370 miles away from the Ukrainian border.
