Iraqi Forces Battle ISIS In Anbar Province As Casualties Mount

BAGHDAD, IRAQ - APRIL 11: Portraits of slain Shia militiamen stand at a mass funeral on April 11, 2015 in Baghdad, Iraq. Pro-government comrades and family members eulogized 15 Badr Brigade fighters who's bodies were collected from the battlefield south of Tikrit, after heavy fighting with ISIS extremists from the area. Shia militia and Iraqi government troops are now preparing for an assault on ISIS forces in Anbar, much of which was captured by ISIS forces last year. Anbar Province was the site of the some of the fiercest fighting between U.S. and insurgent forces before American troops withdrew in 2010. (Photo by John Moore/Getty Images)
