Amnesty International on Monday accused Russia of war crimes in Ukraine, saying attacks on Kharkiv, many using banned cluster bombs, had killed hundreds of civilians.
"The repeated bombardments of residential neighborhoods in Kharkiv are indiscriminate attacks which killed and injured hundreds of civilians, and as such constitute war crimes," the rights group said in a report on Ukraine's second-largest city.
"This is true both for the strikes carried out using cluster (munitions) as well as those conducted using other types of unguided rockets and unguided artillery shells," it said.
"The continued use of such inaccurate explosive weapons in populated civilian areas, in the knowledge that they are repeatedly causing large numbers of civilian casualties, may even amount to directing attacks against the civilian population."
Bombs and land mines
Amnesty said it had uncovered proof in Kharkiv of the repeated use by Russian forces of 9N210 and 9N235 cluster bombs and scatterable land mines, all of which are banned under international conventions.
Cluster bombs release dozens of bomblets or grenades in mid-air, scattering them indiscriminately over hundreds of square meters (yards).
Scatterable land mines combine "the worst possible attributes of cluster munitions and antipersonnel land mines," Amnesty said.
Unguided artillery shells have a margin of error of over 100 meters.
The report, entitled "Anyone Can Die At Any Time," details how Russian forces began targeting civilian areas of Kharkiv on the first day of the invasion on February 24.
The "relentless" shelling continued for two months, wreaking "wholesale destruction" on the city of 1.5 million.
"People have been killed in their homes and in the streets, in playgrounds and in cemeteries, while queueing for humanitarian aid, or shopping for food and medicine," said Donatella Rovera, Amnesty International's senior crisis response adviser.
"The repeated use of widely banned cluster munitions is shocking, and a further indication of utter disregard for civilian lives.
"The Russian forces responsible for these horrific attacks must be held accountable."
'She stood no chance'
Kharkiv's Military Administration told Amnesty 606 civilians had been killed and 1,248 wounded in the region since the conflict began.
Russia and Ukraine are not parties to the international conventions banning cluster munitions and anti-personnel mines.
But, Amnesty stressed, "international humanitarian law prohibits indiscriminate attacks and the use of weapons that are indiscriminate by nature.
"Launching indiscriminate attacks resulting in death or injury to civilians, or damage to civilian objects, constitutes war crimes,” it said.
One of the witnesses Amnesty spoke to had survived cancer, only to lose both her legs in a Russian cluster bomb attack.
Olena Sorokina, 57, was outside her building when flying shrapnel hit her. She lost one leg instantly and the other had to be amputated later.
A neighbor with her was killed on the spot. The latter's daughter said the shrapnel tore through the building.
"Even if mum had been inside her home she would have been hit. She stood no chance in the face of such bombing," she said.
Amnesty investigated 41 Russian strikes that killed at least 62 people and wounded at least 196. It spoke to 160 people in Kharkiv over two weeks in April and May, including survivors, victims' relatives, witnesses and doctors.
Ukraine says it has launched more than 12,000 war crimes probes since the war began.
