WASHINGTON — The Defense Department said Friday that 34 American service members have traumatic brain injuries from Iranian airstrikes on Al Asad Air Base in Iraq, contradicting President Trump’s dismissal of injuries among American troops this week.
A Pentagon spokesman, Jonathan Hoffman, told a news conference that eight of the affected service members have returned to the United States from an American military hospital in Germany.
On Wednesday, Mr. Trump dismissed concussion symptoms felt by the troops as “not very serious,” even as the Pentagon acknowledged that a number of American service members were being studied for possible traumatic brain injury caused by the attack.
“I heard they had headaches,” Mr. Trump said at a news conference in Davos, Switzerland. “I don’t consider them very serious injuries relative to other injuries I have seen.”
Senator Jack Reed, Democrat of Rhode Island and his party’s ranking member on the Armed Services Committee, called on Mr. Trump to apologize for belittling the injuries suffered by the troops.
“It’s plain wrong for President Trump to diminish their wounds,” Mr. Reed, who served as an officer in the 82nd Airborne Division, said in a statement Friday. “He may not have meant to disrespect them, but President Trump’s comments were an insult to our troops. He owes them an apology.”
The comments of the president, who avoided the Vietnam War draft with a diagnosis of bone spurs, also drew criticism from veterans organizations.
“Don’t just be outraged by #PresidentMayhem’s latest asinine comments,” Paul Rieckhoff, the founder of Iraq and Afghanistan Veterans of America, wrote on Twitter the day Mr. Trump spoke in Davos. “Take action to help vets facing TBIs,” meaning traumatic brain injuries.
Traumatic brain injuries can result from the powerful changes in atmospheric pressure that accompany an explosion like that from a missile warhead.
The missiles were launched by Iran in retaliation for the killing of a top Iranian general, Qassim Suleimani, by an American drone strike in Baghdad on Jan. 3. The Trump administration at first said that there were no injuries from the Iranian attack on American troops.
Pentagon and military officials said subsequently that any delay in reporting the injuries was because it took time for the information to work its way up the chain of command to leaders in Washington. Officials also noted that symptoms from brain injuries do not always appear immediately.
Of the 34 service members who were told they have traumatic brain injuries, 17 were flown by medical evacuation aircraft to Germany. Nine remain in the military hospital there, while the others were flown to the United States.
One person was taken by medevac to Kuwait. Sixteen service members were treated for traumatic brain injury in Iraq and have returned to duty, officials said.
