The Pentagon is reporting progress in the fight against ISIS in Iraq and Syria.

FOX's Rachel Sutherland reports from Washington:

A U.S.-led coalition airstrike has taken out an ISIS leader in Iraq:

(Colonel Dorrian) "Abdel Basset al-Iraqi, who was imir of ISIL's Middle East external networks."

Operation Inherent Resolve spokesman Colonel John Dorrian also confirms Turkish-backed Syrian forces are close to retaking the town of al-Bab in Syria:

(Colonel Dorrian) "They've not yet moved in to al-Bab and taken the city but they are very very close, encountering some pretty tough resistance. They do expect to be able to power through that."

U.S.-led forces are also planning to retake the city of Raqqa, Syria, which ISIS sees as its capital.
