The US-led coalition have pounded the Islamic State of Iraq and the Levant (ISIL) group with 31 air strikes, including more than a dozen in the flashpoint Syrian town of Kobane, the Pentagon has said.
The 13 strikes in Kobane, destroyed 19 fighting positions on Friday, as well as ISIL buildings, staging areas and a vehicle, the Defence Department said in a statement.
Several tactical units were also hit by fighter and bomber aircraft, as well drones, the statement said.
Fighting over Kobane began in mid-September, when the ISIL launched a bid to take over the town on the border with Turkey. The US-led coalition has been launching air strikes against ISIL in Syria since September 23.
There were a total of 16 strikes in Syria, where coalition raids also struck a drilling tower, more vehicles, and another staging area.
In Iraq, strikes destroyed an ISIL rocket system near the town of Al Asad in Anbar province.
The jets and drones also targeted ISIL vehicles, fighting positions, equipment, tactical units, and a storage container, in a total of 15 raids across seven locations in Iraq.
