Updated at 7:28 p.m. EDT, May 17, 2009 At least 20 Iraqis were killed and 21 more were wounded in today’s reported attacks. No Coalition deaths were reported. Despite the shrinking number of attacks, Iraqis still worry if violence will explode after U.S. troops leave Iraqi cities. Meanwhile, security forces continue to arrests dozens of Iraqis in operations around the country. Although there is a need to control violent gunmen, some of those captured in these operations could simply be the victims of harassment.
