Around 60 to 90 persons or more,[2] men, women and children – were ordered to take off their clothes and were then massacred by machine gun.

Kisielin massacre was part of a wave of the UkrainianOUN-UPAmassacres of Poles in Volhynia carried out between 1943 and 1944 during World War II. Among its survivors were parents of Polish composerKrzesimir Dębski, who in the early 2000s accompanied his mother to Kisielin. His trip was featured inAgnieszka Arnold's 2003 movieOczyszczenie (Cleansing). Other survivors included also Faustyn Kraszewski, grandfather ofMaria Minakowska, but at least five killed belonged to his family.[4]
The massacre was a subject of a 2009 Polish historical documentary filmByło sobie miasteczko... produced by Adam Kruk forTelewizja Polska.[5] The film recounts the tragic memories of the Polish Catholics originally from Kisielin as well as those of the Ukrainians peasants who remained, but also, it is a reflection on the eradication of Polish culture and tradition in the entire region of Western Ukraine, and the painful legacy that lingers.[5]
