White House spokespeople did not immediately return a request for comment.

“I am pleased to inform you, the American people should be extremely grateful and happy. No Americans were harmed in last night’s attack by the Iranian regime,” Trump said in a televised address to the nation, delivered from the White House in the immediate aftermath of the strike. “We suffered no casualties. All of our soldiers are safe, and only minimal damage was sustained at our military bases.”

But Urban said Thursday that “in the days following” the strike, “out of an abundance of caution,” eight troops were transported from the Al-Asad air base to a medical center in Germany, and another three were moved to Kuwait “for follow-on screening.” He did not specify a timeline for their diagnosis and treatment.

The soldiers’ injuries were first reported by Defense One.

“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 explained.

“When deemed fit for duty, the service members are expected to return to Iraq following screening,” he added. “The health and welfare of our personnel is a top priority and we will not discuss any individual’s medical status.”
