1961 Kurenivka mudslide
The 1961 Kurenivka mudslide occurred on March 13 in Kyiv, Ukrainian SSR, Soviet Union. The mudslide started at the edge of the Babi Yar mass murder site and dumped mud, water, and human remains into the streets of Kyiv. The Soviet authorities suppressed information about the disaster, and claimed 145 people were killed, while forbidding any memorial events for the victims. A 2012 study in Ukraine estimates that the number of victims was closer to 1,500.
