There was more gunfire at a protest in the Iraqi capital of Baghdad on Sunday. It followed a day when least 15 people were killed and 60 wounded when gunmen opened fire in the city's Khilani Square. It was unclear where Sunday's gunfire came from. The violence comes after Iraqi Prime Minister Adil Abdul-Mahdi ordered security forces near protests to disarm and prohibited the use of live ammunition by police in October. At least 400 people have died since the protests began on October 1, decrying corruption, poor services, lack of jobs and calling for changes to the political system.
