These are both storage and production capacities. Every such incident that has disrupted the operation of some facilities over the last few weeks or months also disrupted the pace of the supply of fuels and lubricants to the occupying forces in Ukraine. It gives our Defence Forces extra time and opportunities and helps save civilian Ukrainian lives. Tanks cannot function without fuel. Resurrects the supply of fuel, tanks cannot function without fuel. Recent events clearly show that the process is ongoing and will continue, Yusov added.
