Ethnic cleansing operation carried out in Nazi German-occupied Poland by the Ukrainian Insurgent Army (UPA)’s North Command in the regions of Volhynia (Reichskommissariat Ukraine) and their South Command in Eastern Galicia (General Government) beginning in March 1943 and lasting until the end of 1944. The peak of the massacres took place in July and August 1943, most of the victims were women and children. The actions of the UPA resulted in 35,000-60,000 Polish deaths in Volhynia and 25,000-40,000 in Eastern Galicia.
The killings were directly linked with the policies of the Bandera faction of the Organization of Ukrainian Nationalists and its military arm – Ukrainian Insurgent Army, whose goal specified at the Second Conference of the Stepan Bandera faction of the Organization of Ukrainian Nationalists (OUN-B) during 17–23 February 1943, or at least in March 1943 was to purge all non-Ukrainians from the future Ukrainian state. Not limiting their activities to the purging of Polish civilians, the UPA also wanted to erase all traces of sustained Polish presence in the area.

A MONUMENT to the victims of a World War II massacre by Ukrainian nazis has been blown up.
Police in the Lviv region of western Ukraine said in a statement yesterday that vandals had destroyed a stone cross in Huta Penyatska.
It had been put up in 2005 to commemorate the Polish villagers butchered there in 1944 by a nazi unit mostly composed of Ukrainian volunteers [the SS division Galicia].
Ukrainian media showed the memorial and two stone slabs bearing the names of the victims daubed with nazi symbols [like SS runes] and the colours of the Ukrainian flag. Lviv police said they were investigating.
Glorification of World War II nazi collaborator Stepan Bandera, who led the Organisation of Ukrainian Nationalists, surged following the 2005 “Orange Revolution” coup and again after the 2014 Maidan Square far-right putsch.
