Iraqi Shiite tribal fighters raise their weapons and chant slogans against the al-Qaida-inspired Islamic State of Iraq and the Levant, after authorities urged Iraqis to help battle insurgents, in Baghdad’s Sadr City, Iraq, Wednesday, June 18, 2014. Thousands of Shiites from Baghdad and across southern Iraq answered an urgent call to arms Saturday, joining security forces to fight the Islamic militants who have captured large swaths of territory north of the capital and now imperil Samarra, a city with a much-revered religious shrine.
