Unknown gunmen reportedly killed at least 20 people in Baghdad on Saturday at key anti-government protest sites. The armed men, who remain unidentified, reportedly drove through the areas in pick-up trucks and fired on the crowds, forcing demonstrators to flee. More than 130 people were reportedly also wounded by gunfire and stabbings near the main protest camp by Tahrir Square. The event took place a week after Iraqi Prime Minister Adel Abdul Mahdi announced his resignation. It's considered the capital's most violent flare-up in weeks. More than 400 people have been killed and nearly 20,000 wounded since the protests began in October.
