A Holocaust monument has been vandalized in the city of Poltava, in central Ukraine. The memorial was daubed with Ukrainian nationalistic symbols and anti-Semitic graffiti. Local authorities are investigating the incident, which took place on Monday night. Some Poltava Jews believe that Ukrainian nationalists committed the vandalism, but others say it was organized by anti-democratic forces. The monuments remembers more than 3,000 local Jews who were killed by the Nazis on 23 November 1941, and over 5,000 Red Army prisoners of war and resistance fighters who were murdered in the city during World War II.
