There are also reports that there was not one, but two armored vehicles. A source from the FSB told LifeNews Channel that two armored vehicles crossed the Russian border.
Initially just one APC entered Russian territory, however it broke down, LifeNews was told. It was discovered by the Border Service, however, Russia’s troops failed to take the Ukrainian military personnel captive as another armored vehicle came to the rescue from Ukraine’s Lugansk Region.
After that the Ukrainian troops fled the territory, returning to Ukraine, leaving the dsabled vehicle behind in Russia.
In response to the incident, the Ukrainian Border Service said that the military was surrounded by self-defense forces so they were forced to cross the Russian border to reach new locations of their units, NTV TV channel reported. Border authorities also assured that all 26 border officers returned to Ukraine via another checkpoint.
