An Islamic State militant identified as the group's "finance minister" has been killed in an airstrike as the US and allies continue to target its funding network.
Abu Saleh, whose real name was Muwaffaq Mustafa Muhammad al-Karmush, was killed in late November, US military spokesman Colonel Steve Warren said.
He was described as "one of the most senior and experienced members" of the group's funding network.
IS secures most of its funding from activities in the caliphate it has declared in northern Iraq and Syria, including black market oil sales, extortion and looting financial institutions.
It has made more than $500m trading oil, with large amounts sold to the government of Syrian President Bashar al Assad, a senior US Treasury official said.
