A third night of U.S.-led airstrikes pounded Islamic State-controlled oil refineries in eastern Syria, as the United States and its partners moved to choke off a crucial source of revenue for the militant group, U.S. officials said on Wednesday.
Saudi Arabia and the United Arab Emirates joined in the strikes by piloted and drone aircraft targeting facilities around al Mayadin, al Hasakah, and Abu Kamal, the U.S. military said.
The U.S. Central Command said there were a total of 13 strikes against 12 modular oil refineries controlled by Islamic State fighters as well as another strike that destroyed an Islamic State vehicle.
"We are still assessing the outcome of the attack on the refineries, but have initial indications that the strikes were successful," Central Command said in a statement.
Modular refineries are prefabricated and constructed off-site so they can be transported and made operational quickly. The U.S. military said the refineries were capable of producing millions in revenue and provided fuel for the group's operations.
