STORY: According to the Polish foreign ministry, the missile fell on the village at 3:40 p.m. local time (0240 GMT) after a massive day of Russian shelling of Ukraine.
Polish President Andrzej Duda said later that "it was most likely a Russian-made missile" but that the incident was still under investigation.
A resident who declined to be identified said the two men who were killed were near the weighing area of a grain facility.
Farm worker Mateusz Zub told Reuters:
"How far is it? A kilometer and a half? I saw the smoke pile and heard the blast and that's it. The windows were shaking."
"I called my colleagues because I was weak at the knees. At first I really thought it was a furnace exploding, but then it turned out a rocket had hit them. I have a heart and liver problems, I though I was going to pass out. I went pale in the face. They told me those men are dead... that could've been me. That could've been me."
