New video posted to social media shows at least one man getting hit by gunfire during a protest against the Russian military in the small town of Novopskov in northeastern Ukraine.
CNN has geolocated and confirmed the authenticity of the video.
"People tried to stop the Russians, but they opened fire on the unarmed people. There are three wounded, they are in hospital," according to Sergiy Haidai, the head of the Luhansk regional administration.
CNN cannot confirm the reported casualty figures.
The video from Saturday showed a crowd walking up a street carrying Ukrainian flags and chanting "Ukraine." A man in front of the crowd walked toward troops before shots rang out. He fell to the ground, apparently wounded in the leg.
"Everybody must leave the area now," a voice is heard saying in the distance.
A photograph from the scene showed a man with a bloodied leg being carried away; it appears to be the same individual.
A few sporadic shots rang out, and then a barrage of small arms fire followed as the crowd scatters. It's unclear whether the gunfire is being directed at or above the crowd.
Additional videos from the scene show that prior to the man being shot, the Russian military was firing their guns — not hitting the protesters — and giving apparent warning shots.
One of the videos, taken before the protester was hit, showed the crowd walking forward toward the Russian troops, who have set up camp in an open-air market, surrounded by grocery stores and shop in the center of town.
Despite the gunshots, the crowd did not move.
