Washington: The United States and its allies conducted 22 air strikes against Daesh forces in Iraq on Friday and Saturday, the US Central Command said.

US warplanes also destroyed an Daesh artillery piece near Kobani, Syria, officials said Saturday.

The 22 strikes in Iraq included attacks in the frequently targeted areas near the vital Mosul dam, the city of Fallujah and the northern city of Baiji, home of an oil refinery.

The Iraq strikes hit large and small Daesh units, buildings, vehicles and fighting positions, Central Command said.

The bomber, fighter and remotely piloted aircraft used in the air strikes all returned safely, US officials said.
