Six countries of the former Yugoslavia have agreed to renovate a barracks at the Auschwitz-Birkenau concentration camp run by the Nazis that housed nearly 20,000 Yugoslavs during World War II, the UN's cultural agency said on January 25. The agreement was reached after 14 years of negotiations by Bosnia-Herzegovina, Croatia, Montenegro, North Macedonia, Serbia, and Slovenia. The renovation work of Block 17 at Auschwitz-Birkenau in Poland will include the installation of a joint permanent exhibition on the Holocaust in the former Yugoslavia, which saw the murder of around 66,000 of the country's 80,000 Jews.
