Reuters reports Iraqi security forces fought to rout Islamic State militants from the western city of Ramadi on Wednesday, slowly regaining some ground from the militant group, security and local officials said. The insurgents began encroaching on Ramadi two weeks ago and local officials warned it was about to fall, sending more than 100,000 people fleeing their homes in and around the provincial capital of Anbar. Security officials said Islamic State were being pushed back from sections near the military's Anbar operation command but booby-traps, snipers and suicide attacks were hindering government troops from recapturing other areas they lost last week. "We’re engaged in tough guerrilla warfare in Ramadi," said an Iraqi security officer whose unit is fighting in Ramadi. Speaking on condition of anonymity, he said the militants had dug tunnels between houses so they could carry out hit and run attacks.
