A Russian military expert says that NATO keeps pouring arms into Ukraine despite bombing basic infrastructure like roads and bridges.

This is because of the difficulty of sending special forces deep into Ukraine and the inability of missiles or bombs to hit the bridge columns. Yuri Knutov, the director of the Museum of the Air Defense Troops, stated this while speaking about strikes by Russian Su-34 aircraft.
