The US-backed Syrian opposition forces gained additional territory from Daesh in Manbij, Syria over the weekend.
The opposition recaptured a hospital that was being used by Daesh as a command and control center. This will greatly impact Daesh's ability to regain ground in the region.
"The hospital was contested for some time and it was a signifcant challenge for these forces operating in Manbij to expel (Daesh) from the building without doing major damage," said Pentagon spokesman Peter Cook to reporters on Monday.
"Once the city is secured, the hospital will be returned to local civilian control so it can once again serve city residents."
Due to Daesh movements and Russian airstrikes on civilian targets, many hospitals in Syria have been destroyed. The return of the Manbij hospital to civilians could improve quality of life for thousands of people living in the surrounding area.
