Witnesses told Iran International that security forces used heavy force against protesters in the city of Borujerd, in Iran’s western Lorestan province, including what they described as live ammunition and high-pressure water cannons.
According to the accounts, large crowds gathered on the first night of recent protest calls, with people of all ages taking part.
One witness said security forces fired live rounds and pellet guns at demonstrators, who had little means of defense.
The witness also said authorities used water cannon trucks, drones and aerial surveillance to disperse the crowd.
The account said several civilians were killed that night and many others wounded, though the claims could not be independently verified.
Witnesses said an internet shutdown made it difficult to share images or videos of the events.
