Why is "Art theft and looting by Russia during the invasion of Ukraine" trending?

Wikipedia Overview

Since the 2022 Russian invasion of Ukraine, Russian forces and organizations have stolen and looted tens of thousands of art pieces from Ukraine, ranging from modern art to ancient Scythian gold. The Russians have also destroyed hundreds of cultural sites and monuments. The looting has been organized, with, in some cases, Russian art experts participating in the theft, and directing Russian soldiers as to which pieces to steal. In Mariupol alone, Russians stole over 2,000 works of art from the city's three main museums, after Russian forces occupied the city after a three-month siege in May 2022. In the Kherson region, shortly before fleeing the area to the north of the Dnieper river Russians destroyed, either fully or in part, over 200 Ukrainian cultural sites and stole around 10,000 art pieces from the city's museums, out of a collection of 13,000. Other sources put the number of stolen art works from Kherson alone at 15,000.
