An increase in violence targeting Shi’ite pilgrims added to today’s casualty figures. At least five Iraqis were killed and 41 more were wounded in sectarian and other assaults. Hundreds of thousands of Shi’ites are now traveling to Karbala for Arbaeen observances. Many are on foot, making them more vulnerable; however, the worst attack that occurred was against security personnel in Samarra. Meanwhile, a second prominent Iraqi leader is now threatening to declare a boycott of upcoming elections and perhaps throw the entire country into disarray. Also, the Islamic State in Iraq claimed responsibility for a blast at a crime lab on Tuesday.
