The Levant News -- Iraq's government is under growing pressure to improve security as the death toll from Sunday’s massive car bombing in Baghdad’s predominantly Shiite Karada neighborhood officially topped 200. Prime Minister Haider al-Abadi has announced three days of mourning. He also ordered that phony explosives detection devices be withdrawn from checkpoints, where they offer a false sense of security. The device was found to be a hoax years ago, and its British seller was convicted of fraud in 2013. Meanwhile, Shiite militias are demanding a greater role in proving security in Baghdad, arguing that the regular forces are not up to the job.
