BAGHDAD (AP) - Iran's Revolution Guard says a U.S. drone strike has killed two of its advisers in Iraq, though the U.S. said Monday it has only struck militants in its campaign against the Islamic State group.
The claim came as negotiators on Monday attempted to reach a deal on Iran's contested nuclear program, which hard-liners in the Islamic Republic have opposed as giving away too much to the West.
The Guard said on its sepahnews.ir website the strike happened March 23, just after the U.S.-led coalition began airstrikes to support Iraqi forces trying to retake the Islamic State-held city of Tikrit. It identified the dead as Ali Yazdani and Hadi Jafari, saying they were buried Sunday. It called them advisers, without elaborating on whether Iran contacted Iraqi or U.S. forces after the strike.
Iran occasionally reports on the death of its forces in Iraq and Syria, where it is backing embattled President Bashar Assad, but this is the first time Iran has said it has lost forces in an attack by the U.S. in those campaigns.
The U.S.-led coalition began a campaign of airstrikes and reconnaissance missions around Tikrit, Saddam Hussein's hometown, on March 21 in support of large-scale operations to retake it after Iraqi efforts had stalled.
Reached by The Associated Press, the U.S. Embassy in Baghdad said: "The international coalition is aimed at Daesh only," using an alternate Arabic acronym for the Islamic State group.
"All airstrikes are carried out at the request of the Iraqi government and in full coordination with the (Iraqi) Ministry of Defense," the embassy said, without directly addressing the Iranian claim.
The Islamic State group now controls a third of both Iraq and neighboring Syria. The U.S. began airstrikes against the group in August, while Iran has offered advisers and other assistance to Iraq to fight the extremists.
The offensive to retake Tikrit largely has been waged by Iraqi troops and Shiite militias advised by Gen. Qassem Soleimani, commander of the elite Quds Force of Iran's Revolutionary Guard. Several Shiite militias announced Thursday that they would boycott the Tikrit operations due to U.S. involvement, but Army Gen. Lloyd Austin, head of U.S. Central Command, told a Senate hearing Thursday that the U.S. agreed to Iraqi government requests to support the operation on the condition that the militias wouldn't be involved.
On Friday, Iraqi media outlets reported casualties among Iraqi security forces near the University of Tikrit, allegedly from U.S. airstrikes. But the U.S. Embassy in Baghdad denied those claims, saying "no coalition airstrikes took place during the time or in the vicinity of these alleged casualties."
