Dozens of people, some armed with what appeared to be hunting rifles, clashed in broad daylight on Friday in a residential suburb outside the capital Kiev, and at least three people were wounded, according to officials.
The violence, captured in amateur footage taken from surrounding apartment blocks and posted online, occurred in the morning in Brovary.
According to Interior Minister Arsen Avakov, about 100 people took part in the clashes, some of whom came from another region.
The footage, which we could not immediately verify independently, showed men in masks and dark clothes exchanging fire with hidden adversaries who were obscured by trees. We counted around 40 shots.
President Volodymyr Zelenskiy urged the government to investigate in incident and punish those responsible, the presidential press service said.
“The head of the interior ministry reported to the president that the conflict occurred between representatives of companies involved in passenger transportation in Brovary,” it said in a statement.
Avakov said 20 people were detained.
The interior ministry said that the head of police in the region of Vynnytsya, where some of those who took part in the clashes came from, had been sacked. It was not clear whether the two were related.
