Allegedly in response to the actions of the NKVD, the Germans rounded up all the local Jews they could find, nearly 34,000, and massacred them at Babi Yar in Kyiv on 29 and 30 September 1941. In the months that followed, thousands more were taken to Babi Yar where they were shot. It is estimated that the Germans murdered more than 100,000 people of various ethnic groups, mostly civilians, at Babi Yar during World War II.
