WARSAW, POLAND—Holocaust researchers from Israel’s Yad Vashem and Poland’s Majdanek State Museum announced that they have found the exact location of the building that housed the gas chambers at Sobibór, a Nazi death camp in occupied Poland that killed an estimated 250,000 Jewish people between April 1942 and October 1943. The Germans dismantled the camp during the war, after a prisoner revolt in which several German officers and guards were killed. There were very few survivors. “Any small piece of information we can add to our knowledge is a great thing,” Israeli archaeologist Yoram Haimi told The Associated Press.
