The US-led coalition pounded ISIS with 39 airstrikes Thursday and Friday, including more than a dozen near the flashpoint Syrian town of Kobani.
The 13 strikes conducted Thursday in Kobani, which is known as Ain al-Arab in Arabic, destroyed 17 fighting positions, as well as ISIS buildings, staging areas and a vehicle, the US-led coalition said in a statement.
On Friday, four airstrikes destroyed three ISIS buildings and two vehicles in the area, it added.
The statement updated an earlier report by the US Defense Department, which had erroneously stated that all of the strikes occurred Friday, and which had set the total number of strikes at 31.
Fighting over Kobani began in mid-September, when the jihadists moved to take over the town on the border with Turkey. The US-led coalition launched airstrikes against ISIS in Syria on Sept. 23.
Over Thursday and Friday, there were 19 strikes in Syria by coalition fighter and bomber aircraft, as well as drones.
Coalition raids also struck tactical units, a drilling tower and an assembly area, the statement said.
In Iraq, the coalition carried out 20 strikes according to the updated document: 15 Thursday, mostly in Ninevah and Anbar, two of the main fronts in the fight against ISIS there, and five Friday in the same provinces.
The strikes destroyed an ISIS rocket system and vehicles, equipment, a mortar position, fighting position and a modular refinery.
The jets and drones also targeted ISIS tactical units and a checkpoint.
