In this photo taken on Friday, June 13, 2014, Ammar al-Hakim, leader of Iraq's largest Shiite party, the Supreme Islamic Iraqi Council, exercises a shooting drill in the main army recruiting center in Baghdad, Iraq. 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 a city with a much-revered religious shrine.
