The Ponary Massacre (Polish: zbrodnia w Ponarach) was the mass murder of up to 100,000 people, mostly Jews, but also Russians, Poles, Lithuanians and others, by German SD, SS and Lithuanian Nazi collaborators, such as the Ypatingasis būrys units, during World War II and the Holocaust in Reichskommissariat Ostland. The executions took place between July 1941 and August 1944 near the railway station of Ponary, now known as Paneriai, a suburb of what is today Vilnius, Lithuania.
