As the military operation was still in progress, there were cases of Romanian troops "taking revenge" on Jews in Bessarabia, in the form of pogroms on civilians and murder of Jewish POWs, resulting in several thousand dead. The supposed cause for murdering Jews was that in 1940 some Jews welcomed the Soviet takeover as liberation. At the same time the notorious SS Einsatzgruppe D, operating in the area of the German 11th Army, committed summary executions of Jews under the pretext that they were spies, saboteurs, Communists, or under no pretext whatsoever.
