There is particularly strong evidence that Ukrainian government forces were responsible for several cluster munition attacks on central Donetsk in early October, Human Rights Watch said. In addition to evidence at the impact site indicating that the cluster munitions came from the direction of government-controlled areas southwest of Donetsk, witnesses in that area said that they observed rockets being launched toward Donetsk on the times and days when cluster munitions struck the city.
A New York Times journalist tracked down several rockets in that area, which appeared to have malfunctioned and fallen to the ground shortly after they were launched, clearly establishing the flight path of the rockets.In the 12 incidents documented by Human Rights Watch, cluster munitions killed at least 6 people and injured dozens. The real casualty number from use of cluster munitions in the conflict is probably higher, Human Rights Watch said, since it has not investigated all allegations of cluster munition use. Also, in some cases, it was not possible to determine what weapon caused the death or injury because several types of explosive weapons were used at the same time in the same area.
