The strikes were conducted as part of Operation Inherent Resolve, the operation to eliminate the Islamic State, also known as Daesh, and the threat it poses, according to the release.
In Syria, three air attacks destroyed seven Daesh fighting positions near AL Hawl, the release said. In Iraq, the strikes focused on targets near Hit, Kirkuk, Mosul, Qayyarah and Ramadi.
Targets in Iraq, the release explained, included Islamic State mortar positions, tactical units, a heavy machine gun and three bomb factories.
