(CNN) US Central Command announced Tuesday that additional US troops who were serving at a base in Iraq that was struck by Iranian missiles earlier this month have been transported to an American medical facility in Germany.

CENTCOM did not immediately give an exact number on how many additional service members had been injured in the strike. A Defense official told CNN after the initial 11 service members were evacuated that more injured troops could be identified.

In a statement announcing the development, Capt. Bill Urban, spokesman for CENTOM, said the additional service members were moved "out of an abundance of caution" and that "it is possible additional injuries may be identified in the future."

"As medical treatment and evaluations in theater continue, additional service members have been identified as having potential injuries," Urban said. "These service members -- out of an abundance of caution -- have been transported to Landstuhl, Germany for further evaluations and necessary treatment on an outpatient basis. Given the nature of injuries already noted, it is possible additional injuries may be identified in the future."
