The US military acknowledged Thursday that 11 soldiers were wounded in an Iranian missile strike on a US base in Iraq, despite previously saying that there had been no injuries.

Spokesperson for US Central Command, Capt. Bill Urban, said eight soldiers were transported to Landstuhl Regional Medical Center in Germany and three were sent to Camp Arifjan in Kuwait for “follow-on screening.”

At the time of the attack, most of the 1,500 US soldiers at the base had been tucked away in bunkers, after advance warning from superiors.

Top US officials, including US President Donald Trump and Defense Secretary Mark Esper said several times that there were no US casualties in the missiles strikes on two US bases that came as an Iranian response to the January 3 drone strike that killed senior Iranian general Qasem Soleimani in Baghdad.

Iranians fired a total of 16 missiles strikes, US officials said. Eleven hit the airbase, in Iraq’s western Anbar province, and one targeted the base in Irbil, in Iraq’s semi-autonomous Kurdish region. The missiles were described as likely short-range with 1,000- to 2,000-pound warheads. Four failed to detonate.
