In 1941 at least two groups of Jews were murdered by the Germans on the territory of the tar-processing plant in Hancewicze. The first group consisted of 100 people, while the second one numbered 150. Among the victims were apparently men, women, and children. The Germans finished off those who were still alive with pistols. After the massacre local residents were forced to bury the bodies.\
Aleksandr Zhuk, who was born in 1908 and lived in Hancewicze during the war years, testified:
During all the time of the German occupation I lived on the territory of the tar-processing plant near Gantsevichi (Hancewicze). I witnessed the Germans occupying Gantsevichi in 1941 and at dawn I took one group of Jewish families, compising about 100 people, to the tar-processing plant. They [the Germans] shot all of them, and finished off those who were [just] wounded or still alive with pistols. After that another 150 people were brought. Then the Germans forced me and my neighbors to bury the bodies of those who had been shot to death. All the 250 shooting victims were thrown into two pits. There are about 20 such pits near Gantsevichi village.
