Masked anti-government gunmen hold their weapons as they patrol Fallujah, Iraq, Saturday, Feb. 15, 2014. Iraq is undergoing a surge in violence unseen since 2008 that has become the Shiite-led government's most serious challenge. Violence has spiked since last April, when security forces cracked down on a Sunni protest camp north of Baghdad in clashes that left 45 dead. Al-Qaida-led militants are battling for control of mainly Sunni areas to the west of the Iraqi capital in a key test of the Shiite-led government's ability to maintain security in the country more than two years after the withdrawal of U.S. troops.
