Geneva, 11 October 2022 (dpa/MIA) - The spate of recent deadly Russian attacks on Ukraine could be classed as war crimes, the UN Human Rights Office in Geneva said on Tuesday. "Attacks targeting civilians and objects indispensable to the survival of civilians are prohibited under international humanitarian law," spokeswoman Ravina Shamdasani said. "The location and timing of the strikes - when people were commuting to work and taking children to school - is particularly shocking," she added. In addition to putting civilians in harms way with strikes on city centres, 12 energy companies and other important infrastructure were hit, the office said. Attacking power plants just before winter hits particularly vulnerable people who are unable to flee because of their age or illness, Shamdasani said. Ukrainian authorities on Tuesday spoke of 19 dead as a result of the attacks on Monday. The UN Human Rights Office called on Russia to refrain from further escalation and to do everything in its power to avoid civilian casualties and damage to civilian infrastructure.
