Footage recorded by a Mariupol local, shows the devastating aftermath of a Russian artillery barrage that struck the city center on March the 10th.

After reviewing some Russian indirect fire footage, it would appear to me that this massive crater was caused by a 3M-54 Kalibr Cruise Missile. At this time, there is no way to confirm or validate the exact explosive device utilized, but in my opinion, there is no way a BM-21 Grad strike would leave a 30-foot diameter crater, UNLESS, it hit something to cause a secondary explosion (gas pipe, sewage line, etc.).

As the cameraman pans to his right, take note of how much damage this single explosive device caused to the building nearly 40-feet from the impact site.
