Transcript for Inside The Fight Against ISIS in Iraq
Overseas tonight, to an ABC news exclusive. On the ground with American troops fighting Isis in Iraq, six people killed today there in a suicide bomb attack outside Baghdad. This week alone, more than a hundred dead in a string of bombings. Our team traveling into the heart of the battle zone and ABC's Martha Raddatz takes us inside this fight. Reporter: We arrived at the Al Assad airbase 150 miles west of Baghdad. To meet the U.S. Marines on the fight against Isis. It's been very very different, how we are doing it through and by the Iraqi military. Reporter: And leading the charge on the ground, these elite Iraqi counterterrorism forces. Their goal -- recapture mosul, Iraq's second-largest city and Isis' de facto capital in Iraq. They train for an assault. Rappel down buildings. And set off an explosion. This may be an exercise to train all these new recruits, but these counterterrorism forces have been in the fight for year. On Friday, we got a firsthand view of what that fight means, driving to ramadi recaptured from Isis just months ago. In the rubble, thousands of hidden bombs. So, Martha, when you and your crew are out walking around, please do not leave any hard surface or pavement. Reporter: Despite the dangers, a small number of the families that once lived here are now returning, children make peace signs from their balcony. Isis held this town for about eight months, and finally the Iraqis were able to retake it, but taking mosul back will be a much bigger challenge. Back at the base, the U.S. Land forces commander Gary Volesky explains how dire the situation in mosul is. People that try to leave mosul are being executed. My assessment in mosul is getting worse and worse every day. Our thanks to Martha and her team for that report.
