In 1943, at least a dozen Poles were murdered in Moszków by the Ukrainian army. Among the victims was Tomasz Bednarczuk, murdered along with his wife, while their 12-year-old son survived. Many years later, in 2001, the son found his father's corpse buried in the garden of his house. The found remains were buried in the Ostrów cemetery.

In the same cemetery is the grave of Aniela and Ludwik Krawc, murdered by the Ukrainian Insurgent Army on 31.03.1944. They died during an attack on the village by the Ukrainian Insurgent Army, during which about 80 people lost their lives.
