(Ahlul Bayt News Agency) - The incident happened when 4,000 people had gathered in Liberation Square in the center of the town of Sulaymanieh, some 270 kilometers (173 miles) north of Baghdad after Friday prayers.
Clashes erupted after some people hurled stones at the police guarding the area. The police responded with batons.
Medical sources at the Sulaymanieh hospital said that most of those injured were policemen.
The injured also included at least one protester and a journalist working for a media outlet linked to Iraqi President Jalal Talabani's Patriotic Union of Kurdistan (PUK).
Kurdistan is dominated by just two parties: the PUK and the regional president's Kurdistan Democratic Party.
Sulaymanieh -- Kurdistan's second largest city -- has seen near-daily protests since February 17. Protesters are demanding the ouster of the regional government as well as an end to corruption.
