Iraqi faction Kataib Hezbollah has said any attack on Iran would directly threaten its own interests and could trigger a regional confrontation An Iran-backed Iraqi armed group has ordered its fighters to prepare for a potential “long war of attrition” in the event of US strikes on Tehran, warning that Washington would suffer heavy losses if it launches a new conflict in the region.The statement by Kataib Hezbollah comes after a third round of indirect US-Iran nuclear talks in Geneva ended without a deal, and as Washington continues to deploy additional warships and aircraft to the Middle East.In a statement on Thursday, the group’s operations command said that “amidst the American threats and military buildup that foreshadow a dangerous escalation in the region,” it was necessary “to prepare for a potentially protracted war of attrition, exceeding the American administration’s estimates.”“Should America, the embodiment of evil, ignite the flames of war in the region, it will find itself facing immense losses that will be impossible to contain or compensate for,” the statement reads.
