The National Library of Israel released the pictures that include the bones of victims, as Ukraine revamps its approach to the tragedy

Ukraine on Wednesday marked the 80th anniversary of the Babi Yar massacre, the mass shooting of nearly 34,000 Jews during the Holocaust, but the biggest development this year may have taken place online: the release of photos showing Soviet Jews uncovering mass graves.

Babi Yar, a ravine in the Ukrainian capital, Kyiv, is where the tens of thousands of Jews were killed within 48 hours in 1941 when the city was under Nazi occupation. The killing at the site, known as Babyn Yar in Ukrainian, was carried out by SS troops and local collaborators.
