Ukrainian marines say they've tracked and killed Russian troops in Donetsk

This footage shows how marines tracked and killed Russian soldiers hiding in damaged buildings in the Donetsk region of eastern Ukraine, according to Ukrainian forces.

The images were obtained from the 503rd Separate Marine Corps Battalion of the Ukrainian Navy on August 20, along with a statement saying: "The closer to Independence Day, the more actively the Russians are trying to seize our land.

"They come in small groups, try to gather strength, thinking that we don't know about them, or we won't see them. But, they still don't understand who they are dealing with. Well, now they will find out for themselves why we have such fertile black soil because people like them are buried four layers deep."
