A dozen rockets hit the Erbil Air Base in Iraqi Kurdistan late on Monday, killing a civilian contractor and hurting nine other people, including a US serviceman. A small Shiite militant group reportedly claimed the attack.

“Iran not only strongly rejects these rumors, but also flatly condemns suspicious attempts to attribute the attack to Iran,” Saeed Khatibzadeh was quoted as saying by the ministry.

He argued that Iran views Iraq’s security as key to the regional stability and “dismisses any move that would disrupt tranquility and order in this country.” He urged the Iraqi government to deal with forces behind the attack.
