"A wandering military convoy with heavy weapons. Most likely, another rotation in the 'commissary' or in the 'Donbas mines,'" officer of the 53rd separate mechanized brigade of the Armed Forces of Ukraine Anatoliy Shtefan wrote on Facebook, posting the relevant footage.

The convoy spotted in Russia's Rostov region was transporting heavy weaponry whose use is prohibited in Donbas by the Minsk peace agreements.
