From the Lenta article:
... the militia was able to “open” the border in the Luhansk region between Russia and Ukraine for free movement of people and vehicles.
In parallel, in the last week of the militia group, 20 people managed to destroy several Ukrainian radar thus depriving the Ukrainian army control over part of its airspace.”
First I have heard of this. Several tweets have noted that there have been “a few” attacks on Ukraine border outposts, from the Ukraine side, in recent days.
