This is a pile of fragments of Russian rockets that hit Ukraine’s 2nd largest city, Kharkiv.
Putin was placing a special hope on this city declaring secession from Ukraine because it has the most Russian speakers statistically than any other in Ukraine.
But after those plans failed and Kharkiv residents went on massive pro-Ukrainian demonstrations instead, Russia began shelling it with rockets.
Reportedly 1/3 of the city is in pretty much in ruins today.
