The Defense Department added 37 people to its public list of U.S. personnel injured in the conflict with Iran this week without explaining the causes of the injuries. This increase brings the total number of wounded service members to 861 as reflected in the Pentagon's official database.

The latest casualties include 29 Navy sailors and eight Marines. While the Defense Department has not provided details on when or how these personnel were hurt, the Navy stated that the affected sailors have already returned to duty.
