Exclusive: A crypto-based dossier could help prove Russia committed war crimes

In early March, a Telegram user posted a photo of wreckage at a school in a suburb of Kharkiv, Ukraine. The photo showed the side of a classroom with a large blast hole and a pile of debris including desks and chairs.

International law prohibits intentional attacks on educational facilities. That means the picture could serve as evidence of a potential war crime, according to Starling Lab, a research center affiliated with Stanford University and the USC Shoah Foundation.

Together with a team of human rights experts and specialist lawyers, Starling submitted evidence of this attack and four others on Friday to the International Criminal Court, which has opened an investigation into allegations of war crimes in Ukraine in the months following Russia's invasion in late February.
