DAMASCUS, Syria -- DAMASCUS, Syria (AP) — Syria started the process of circulating new currency bills on Saturday as the crisis-hit nation seeks to stabilize the economy as it recovers from the fall of Bashar Assad’s government.

Jordan confirmed that its air force took part in the U.S. air strikes "targeting several ISIS positions in southern Syria."

The clashes came two days after a bombing at an Alawite mosque in the city of Homs killed eight people and wounded 18 others during prayers.

At least four people have been killed and dozens wounded in clashes on Syria’s coast in the aftermath of the deadly bombing of an Alawite mosque.

The airstrikes on ISIS targets are being conducted in response to the killing of two U.S. Army soldiers and an civilian contractor by a lone terrorist in Palmyra, Syria.

U.S. Central Command, which oversees the Middle East, said 11 missions were carried out over the past 10 days.

“If Syria fails to integrate all armed forces and former opposition groups into its army, it faces an existential challenge of fragmentation and disintegration,” Caroline Rose, director of military and national security priorities at the New Lines Institute, told Al Jazeera.

Three rockets hit the Mazzeh area of the Syrian capital Damascus on Saturday, local authorities said, adding that one damaged a mosque and another landed near a military airport. Syria's official SANA news agency had earlier reported that an unidentified missile had struck the area without causing any casualties.
