Unidentified vandals have spray-painted Nazi graffiti at a memorial cemetery in Ukraine where some Poles are buried.

Ukrainian Foreign Minister Pavlo Klimkin denounced the vandals' action Wednesday at the Bykivnia memorial on the outskirts of Kiev, the Ukrainian capital. Bykivnia is a burial place for victims of the Soviet secret police, including some Poles, who were executed in the 1920s-1940s.

Vandals spray-painted the name of SS division Galicia, a Nazi unit consisting of Ukrainian volunteers, on one tombstone at Bykivnia. They also put the name of UNA-UNSO, a Ukrainian far-right nationalist organization.

Poland and Ukraine have friendly ties, but some in Poland harbor bitter memories about the killings of up to 100,000 Poles by Ukrainian nationalists in 1943-1944 in Volyn and the eastern Galicia regions, which are now part of Ukraine.
