Human Rights Watch investigations documented that unguided 122mm Grad rockets fired by Ukrainian government forces killed at least 16 civilians and wounded many others in insurgent-controlled areas of Donetsk between July 12 and 21, 2014. Grad rockets, launched from multiple rocket launcher systems with a range of 1.5-20 km and inaccuracy of up to 336x160 meters, are considered indiscriminate weapons when used in populated areas. Impact craters, rocket remnants, and attack directions aligned with Ukrainian force positions near the front lines. Key incidents include: July 21 - rockets near Donetsk railway station, 3 civilians killed; July 19 - five rockets in Kuibyshivskyi district west of Donetsk, at least 4 civilians wounded; July 12 - Petrovskyi district, 7 civilians killed including a family of four; July 12 - Maryinka village, 6 civilians killed and 15 wounded. The use of such inaccurate weapons in densely populated areas violates laws of war that prohibit indiscriminate attacks and those causing excessive civilian harm relative to military advantage. Such acts may constitute war crimes if intentional or reckless.
