On a quiet industrial estate in Kharkiv, the mangled and charred remains of more than 1,000 Russian rockets and artillery shells are being collected.Each chunk of metal evidences the scale of Moscow’s daily long-range attacks on Ukraine’s second-largest city and the surrounding region.When The Telegraph visited the “graveyard” for Russian missiles, Dmytro Chubenko held one particular remnant of a strike on a civilian target aloft. “It is difficult to damage a tank with such a projectile, but it is easy enough to kill people,” the spokesman for Kharkiv’s regional prosecutor said. Since the beginning of the war, some 1,500 civilians have been killed, and 2,500 more wounded, in the northeastern region by Moscow’s forces.War crimes investigators have painstakingly gathered up each and every weapon used against civilian targets in Kharkiv.Banned cluster bombs, Iskander cruise missiles, artillery shells and non-guided rockets that once rained down on built-up residential areas have been laid out for further inspection. The total value of the weapons which were used in these alleged civilian strikes is said to be more than $100 million (£86 million).Some are more intact than others, explained Mr Chubenko, demonstrating Russia’s use of old and failing weapons.Among the wreckages are what appeared to be banned cluster bombs, which scatter dozens of bomblets indiscriminately over hundreds of square metres.Elsewhere lies the twisted remains of an Iskander cruise missile recovered in almost 100 pieces, its casing, jet engine and circuit boards all discovered broken apart, from a deadly strike on Kharkiv’s city hall.Dozens of artillery shells are also among the devastation in Saltivka, a vast Soviet-era housing estate, in northern Kharkiv, which was bombarded in the initial months of the war.Every weapon here was aimed at the city of Kharkiv, with most marked with the exact details of the attack, including death toll, geographical location and more specific details on the hardware.There are also a number of other similar secretive stores for munitions retrieved from attackson the wider Kharkiv region.“These remains of ammunition are material evidence of Russia’s armed aggression against Ukraine,” said Mr Chubenko.“The physical presence of these remains illustrates the scale of the situation, but also record violations according to international and Ukrainian regulations.”
