According to the leader of DNR [Donetsk People’s Republic] terrorist organization Aleksander Zakharchenko, Russian troops crossed Ukrainian-Russian border many times to help the so-called rebels to fight for their ‘freedom’.
According to the warfare code, in the situation when troops cross the border of another country it should be called full-scale military invasion, isn’t it?
Thousands of Russian soldiers have already crossed Ukrainian border. We do not deal with rebels. This is war, although hybrid one.
