A top Pentagon spokesman said Aug. 3 that U.S. and coalition pressure against the ISIS stronghold in Mosul, Iraq, has taken such a toll on militant commanders that they've cut off most communications from the city, including Internet access for civilians there.
Army Col. Chris Garver, the spokesman for Operation Inherent Resolve which is battling ISIS in Syria, Iraq and Libya, told reporters that morale among the ISIS fighters and the civilians being held in Iraq's second largest city is cracking.
"We know that [ISIS] has started cutting off Internet access and really access to the outside world for the citizens inside Mosul," Garver said. "We know that they're afraid that Iraqi citizens inside Mosul are going to communicate with the Iraqi Security Forces."
"We've seen that fear in ISIS in Ramadi, and in Fallujah and we're seeing those indicators inside Mosul as well," he added.
The crumbling situation for rebel forces inside Mosul comes as U.S., Iraqi and Syrian Democratic forces continue to squeeze ISIS in the east of Iraq and to the north in Syria, with nearly half of the critical junction town of Manjib, Syria, taken from ISIS and troops flowing into the newly recaptured Q-West airfield near Mosul.
Top defense officials have hinted the assault on Mosul could launch as soon as the fall and could deal a crushing blow to ISIS worldwide.
"We know that [ISIS] considers Mosul one of the two capitals of the so-called caliphate ... and clearly all eyes are focused on Iraq," Garver said. "So not only would it be a significant physical loss, but the loss of prestige ... their reputation as they try to manage it is going to take a big hit when Mosul does fall."
Garver added that commanders believe there are about 5,000 ISIS fighters in Mosul, with the net tight enough that only small numbers of fighters can get in but not convoy-loads of them.
"At the heyday we saw 2,000 foreign fighters a month coming through Syria," Garver said. "Now we have estimates of between 200 and 500."
As Iraqi forces build out the Q-West airfield to support troops there, the noose will tighten around the city and the takedown will begin, Garver added.
