Dolphin bodies spotted on Mariupol beach

That’s according to Petro Andriushchenko, the adviser to the mayor of Mariupol in exile, who reported the news on Telegram, posting a corresponding video.

"Dead dolphins on the beach. A rusty Azov train. Destroyed children’s rides. Historical stairs turned into stones. This is what ‘Russian Spring’ in Mariupol looks like," he wrote in the captions to the video.

As reported, Russia's aggression caused a major humanitarian disaster in Mariupol. Almost 90 percent of the city was destroyed as a result of enemy shelling. Residential buildings, hospitals, schools, kindergartens, and other infrastructure facilities were either damaged or destroyed.

Currently, more than 100,000 residents remain in the captured city.

Russian invaders released sewage into the stream flowing into the Sea of Azov near the local industrial port.

The invaders are turning Mariupol and the surrounding villages into a military-logistics hub for the Russian army.
