[Editor’s Note: Since the U.S.-led coalition has expanded its airstrikes against Daesh, we have talked about one of the key ways to hurt the Islamic State: targeting its finances. Be it destroying oil trucks or its cash reserves, if you cripple an enemy’s ability to pay for its war, you’re making headway]

Airstrikes by the U.S.-led coalition  blew up a warehouse in Iraq where the Islamic State had stored millions of dollars in cash, the U.S. military disclosed Tuesday.

Coalition aircraft targeted a “cash distribution center” near Mosul, Iraq’s second largest city, which is under control of the extremist group, the U.S military said in a daily report on details of airstrikes.

The coalition struck the facility Monday as part of intensified efforts to destroy funding sources of the Islamic State, also known as ISIL or ISIS.

A senior Defense official said the coalition has targeted similar facilities in the past. The official, who is not authorized to discuss the strikes publicly, said coalition aircraft dropped two 2,000-pound bombs on the building. Mosul has been under Islamic State control since 2014, when the militants swept into Iraq from Syria.

In recent months, coalition airstrikes have targeted oil production and distribution centers in territory the Islamic State controls in Syria, reducing the group’s daily oil revenue to less than $1 million from a peak of about $1.3 million.
