According to a US statement, the airstrikes hit 14 different areas in Iraq, including the destruction of a massive bomb and a bomb-making factory in the town of Hit, some 30km west of Ramadi in Anbar province.
Hit town is a strategic site that ISIS has used as a base in order to attack other areas of Iraq.
Coalition airstrikes also hit seven areas in Syria's ethnically Kurdish northeastern region around the liberated city of Kobane.
