Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]

The camp was liberated on April 15, 1945, by the British 11th Armoured Division.[4] The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill,[5] and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied.[4] The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
