In Iraq, security forces have been going door to door, searching homes in areas of the capital Baghdad after three U.S. contractors went missing. The three U.S. citizens were reportedly kidnapped by militiamen from an apartment described by some Iraqi authorities as a brothel. Meanwhile, a new U.N. tally describes a “staggering civilian death toll” from violence in Iraq, with nearly 19,000 civilians killed from the beginning of 2014 through October.
