Masked gunmen opened fire at Iraqi protesters in the Shiite holy city of Karbala on Tuesday, killing 18 people and wounding hundreds, security officials said, in one of the deadliest single attacks since anti-government demonstrations erupted earlier this month. The overnight attack came as Iraqis took to the streets for a fifth straight day after a hiatus in the demonstrations that began earlier this month to protest government corruption, a lack of jobs and municipal services and other grievances. The earlier protests also saw violence against protesters, and a total of 240 people have been killed since the unrest began.
