Firstly there was a large Kaliber missile strike on Lyvov and we are now seeing confirmations from several places of what was struck:
“A stockpile of American, German and British anti-tank missiles was destroyed at a military depot in Lvov. According to our source in the SBU, the attack on the logistics base in Lvov was a complete surprise. Several tens of tons of various anti-tank weapons were destroyed at the facility, including German PanzerFausts, British NLAWs and American Javelins.
It was expected that these funds should be enough for a month of active hostilities against Russian troops. According to our source, the plant was carried out secretly on commercial and civilian vehicles. Therefore, an investigation is now underway as to why the Russians were able to figure out all three storage sites.”
