Several US service members were injured during last week's Iranian missile attack on Al-Asad airbase in Iraq despite the Pentagon initially saying that no casualties had taken place.
"While no U.S. service members were killed in the Jan. 8 Iranian attack on Al Asad Air base, several were treated for concussion symptoms from the blast and are still being assessed," the US-led military coalition fighting ISIS in Iraq and Syria said in a statement Thursday.
"Out of an abundance of caution, service members were transported from Al Asad Air Base, Iraq to Landstuhl Regional Medical Center in Germany for follow-on screening. When deemed fit for duty, the service members are expected to return to Iraq following screening," the statement added.
A US military official told CNN that 11 service members had been injured in the attack, which was launched in retaliation for the US airstrikes that had killed Iranian Gen. Qasem Soleimani the previous week. Defense One was first to report on the injured service members.
Following the attack the Pentagon said that no casualties had resulted from the 16 missiles fired by Iran. The US military defines a casualty as either an injury or fatality involving personnel.
Asked about the apparent discrepancy, a Defense official told CNN, "That was the commander's assessment at the time. Symptoms emerged days after the fact, and they were treated out of an abundance of caution."
"We corrected the record today," Jonathan Hoffman, the chief Pentagon spokesman, told CNN. The Office of the Secretary of Defense "learned about these injuries today and directed a statement go out immediately."
Later on Thursday night, Capt. Bill Urban -- the spokesperson for US Central Command, which oversees troops in the Middle East -- said eight individuals were transported to Landstuhl Regional Medical Center in Germany and three were sent to Camp Arifjan in Kuwait for "follow-on screening."
"As a standard procedure, all personnel in the vicinity of a blast are screened for traumatic brain injury, and if deemed appropriate are transported to a higher level of care," Urban said in a statement. "All soldiers in the immediate blast area were screened and assessed per standard procedure, according to the Defense Department. ... When deemed fit for duty, the service members are expected to return to Iraq following screening."
Last week, Secretary of Defense Mark Esper had said the initial assessment found only damage to property.
"The current (Battle Damage Assessment) is, if you will, again, we can get you details, things like tentage, taxiways, the parking lot, a damaged helicopter, things like that; nothing that I would describe as major, at least as I note at this point in time. So that's the state of -- of the attack at this point as we know it. Most importantly, no casualties, no friendly casualties, whether they are US, coalition, contractor, etc.," Esper said.
The news of the injuries come after Iran fired at two Iraqi bases housing US troops in retaliation for Soleimani's killing in the Iraqi capital of Baghdad. The administration sought to cast its strike on Soleimani as an attempt to de-escalate tensions with Iran, but Tehran has described it as an "act of war" and "state terrorism." Soleimani had been the second most powerful official in the country.
US officials have offered differing accounts of what they see as the motivations behind Iran's attack. Vice President Mike Pence said last week that the administration believes the strikes "were intended to kill Americans," and Army Gen. Mark Milley, the chairman of the Joint Chiefs of Staff, said he believed that the attacks "were intended to cause structural damage, destroy vehicles and equipment and aircraft, and to kill personnel."
But a growing belief emerged among administration officials last week that Iran had deliberately missed areas populated by Americans. Multiple administration officials told CNN that Iran could have directed its missiles to areas populated by Americans, but intentionally did not. And those officials said Iran may have chosen to send a message rather than take action significant enough to provoke a substantial US military response, a possible signal the Trump administration was looking for a rationale to calm the tensions.
Iraq did receive a warning that the strike was coming and was able to take "necessary precautions," according to a statement from Iraq's Prime Minister Adil Abdul Mahdi. A US defense official said that Iraq, in turn, warned the United States.
Iran's UN ambassador said last Friday that the Iraqi bases housing US troops had been primarily selected to demonstrate target accuracy, not to kill Americans, disputing public claims made by top Trump administration officials.
"We said before we took our military action that we would choose the timing and the place, and we chose the place where the attack against Soleimani was initiated," Ambassador Majid Takht Ravanchi told CNN's John Berman on "New Day" last Friday when asked about Pence's comments. "And we do not consider a high number of casualties as an instrumental element in our calculations."
