Sixteen people were killed and 45 others wounded in the Iraqi capital on Friday when unidentified assailants opened fire on anti-government protesters, a source in the interior ministry said.

The attackers entered Baghdad's al-Khalani Square in a convoy of four-wheel-drive vehicles and started shooting at people gathered there for a demonstration, the source told Efe, speaking on condition of anonymity.
