On Friday, May 22, 1942, the first day of the Jewish holiday of Shavuot, the town was surrounded by the German Gendarmerie (rural Order Police) and the Ukrainian Auxiliary Police. The policemen managed to catch and detain more than 1,000 Jews – mainly women, children, and elderly individuals – driving them out of their houses into the street. After being assembled, the Jews were led under reinforced guard to a former brick factory located on the outskirts of the village of Dyvan and near the village of Nevirkov (both lying some 7 kilometers north of Międzyrzecz). Upon reaching the murder site, the Jews were ordered to take off their clothes and enter the pits in groups of 10. As soon as the first group of victims was shot in the back of the head by an SD detachment from the city of Równe, another group would be ordered to lie down on top of the victims, and be shot in the same manner. The executioners used machine guns. The Jewish men and young boys were shot in one pit, while the women and young girls were shot in another pit; the little children were shot in a third pit, and some of them were buried alive. Men of the 1st Company of the 33rd Reserve Police Battalion also took part in this murder operation.
Some Jews from Międzyrzecz, who used to perform forced labor near the village of Nevirkov, were killed along with the other Jewish victims. The murder operation lasted from 10 AM until 12 PM. Immediately after the shooting, the pits were covered with a layer of lime, and a layer of earth was added on top of each pit.
According to a testimony, sometime between May and September 1942, 20 Jews from the nearby village of Matievka were brought to Międzyrzecz. After being held in the town for several days without food or water, they were apparently taken to the former brick factory and shot there.
On September 26, 1942, during the Sukkot holiday, the ghetto was surrounded by the German Gendarmerie and the Ukrainian Auxiliary Police. The remaining inmates of the ghetto were taken to the former brick factory and killed there. They were shot in the back of the head by an SD unit from the city of Równe, who used machine guns. The victims were buried at the site.
