Bloemfontein - Police fired rubber bullets and used stun grenades to disperse striking Metsimaholo municipality workers in Sasolburg, Free State police said on Wednesday.
“The workers threw stones at the municipal building during Wednesday morning,” Sergeant Sellwane Mapamela said.
Strikers damaged the municipal building and a nearby clinic.
Workers began striking this week over salaries and benefits. Some services such as refuse removal had suffered.
Mapamela said the situation was calm on Wednesday afternoon. Police were on the scene.
