BAGHDAD (Reuters) - An Iraqi policeman was killed and seven others wounded in clashes with protesters loyal to prominent Shi'ite cleric Moqtada al-Sadr who had gathered in Baghdad on Saturday to demand political reforms, the interior ministry said.

Thousands had gathered in the central Tahrir Square to demand an overhaul of a commission that supervises elections ahead of a provincial poll due in September.
