US-led forces will probably need up to five more days to finish clearing Fallujah of rebels after a week of fierce fighting that left more than 1,200 insurgents dead, US marine officers said today.

A U.S. Army soldier guards the remains of a burned-out military ammunition truck after it was attacked in Fallujah, Iraq, on Oct. 19, 2003. Fallujah and its surrounds were the site of some of the bloodiest fighting for U.S. troops during the Iraq war.

****ATTN DAVID FURST****PICS FROM FALLUJAH BY BRYAN DENTON FOR THE NYTIMES TRAX: 30191725A 6/25/2016 Fallujah, Iraq Iraqi Special Forces advanced into the al-Jolan district of Fallujah, as smoke from airstrikes and artillery rose in the background. Iraqi Security Forces began their push on the ISIS held city of Fallujah on May 23, and have taken back much of the city. As of Wednesday, June 25, Iraqi Security forces had taken back much of the southern and central districts of the city, but ISIS remains in the north western district of the city, known as al-Jolan. The offensive has sent tens of thousands of residents fleeing into the scorching deserts of Anbar province seeking shelter. The Iraqi government has been strict about not allowing many of them to travel the relatively short distance to Baghdad, and has detained many of the men considered to be of “military age,” in some cases, as young as 12 years old. Many of the men have been brought to “screening centers” run by the government where families fear their loved ones are being tortured or worse. Credit: Bryan Denton For The New York Times
