Raqqa, Syria (CNN) CNN has gained rare access inside the Old City of Raqqa, as rebels and international forces tighten their grip on the final bastion of ISIS' de facto capital. US-led airstrikes breached the 1,300-year-old Rafiqah Wall on Monday , and CNN is the first Western media organization to film inside the fortification since then. After pushing through one of two small gaps in the wall, on the southern edge of city, CNN met with US-backed rebels who are leading the assault. Fighters have have seized control of territory around 300 meters into the Old City since Monday, and CNN saw US forces in this area. It appears these forces have been calling in the airstrikes that led to the advances.
