A video published on the Twitter social network shows what it looks like when a Russian plane is hit by Ukrainian forces.
In these images, the helicopter seems to be hit from a distance, and begins to take a wobbly direction.
On October 1, Ukrainian forces entered the city of Lyman in the Donetsk region, and the next day completely cleared the city of the Russian army.
The liberation of the town of Lyman comes as Russian President Vladimir Putin announced the annexation of four Ukrainian regions, a decision condemned by Western countries.
