"As a result of the conflict, seven police officers from Donetsk region have sustained different body injuries and are in hospital now," chief of police in Donetsk region Viacheslav Abroskin has said.
At about 19:00 local time on Tuesday, a column of 13 vehicles with over 35 men was moving through the entry checkpoint of the Ukrainian-held town of Sloviansk, which was occupied by Russia's hybrid troops April through July 2014.
Police officers wanted to check firearms licenses as the vehicles were entering the Anti-Terrorist Operation zone, but the individuals declined to show their documents, the National Police's main department in Donetsk region said.
"A verbal argument has turned into a brawl during which citizens did not let policemen fulfil their official duties to ensure public security," it said.
In addition, a Member of Parliament, who was at the scene, began to attack police officers and tried to seize their arms. Yet, the police report did not mention his identity.
