About 140 U.S. troops have been wounded in conflict with Iran over 10 days, the Pentagon said Tuesday.

“The vast majority of these injuries have been minor, and 108 service members have already returned to duty,” Pentagon spokesman Sean Parnell told Fox News. “Eight service members remain listed as severely injured and are receiving the highest level of medical care.”

These numbers came after retaliatory Iranian rocket and drone strikes that also killed seven soldiers in Kuwait and Saudi Arabia.
