U.S.-led coalition forces are hammering the Islamic State in Iraq and Syria (ISIS) with a new round of airstrikes.
U.S. Central Command said the U.S. and partner nations launched 31 strikes against targets in both Iraq and Syria on Friday.
The strikes destroyed a number of ISIS buildings, training areas and vehicles, according to a statement on Saturday.
"The destruction of ISIL targets in Syria and Iraq further limits the terrorist group's ability to project terror and conduct operations," said Central Command, using an alternate name for the terror group.
Most of the strikes in Syria were aimed near the ethnic Kurdish town of Kobani, near the Turkish border. The town has been under siege from ISIS for months. According to the military, the airstrikes near Kobani hit 19 ISIS fighting positions, including two large units of fighters.
In Iraq, the strikes were spread over a number of areas, including Sinjar, where ISIS fighters had trapped members of the ethnic Yazidi sect and Mosul, the country's second largest city.
The fall of Mosul this summer sparked fears that ISIS fighters would advance on Baghdad.
The cost of U.S. operations against ISIS since August recently passed the $1 billion mark.
