What is being blown up in the video below?

ANSWER: The Russian amphibious landing ship "Orsk," which was designed to carry 300 to 400 troops and 20 tanks or armored vehicles. Where is it being blowing up? In the Ukrainian port city of Berdyansh, which was captured by Russian forces on February 28. Were any other Russian ships damaged? Yes, two other Russian ships are said to have been either damaged or destroyed. The port's fuel depot is also said to be on fire. What does this mean? It means that it will now be even harder for Putin's invading army to take over the besieged Ukrainian city of Mariupol.

Ukrainian Armed forces report that between February 24 and March 23 (so within one month), the Russian invaders have lost 15,800 troops, 530 tanks, 1,597 armored combat vehicles, 280 artillery systems, and 47 anti-aircraft weapons.
