The number of US service members diagnosed with traumatic brain injuries has shot up to more than 100, the Pentagon said Monday, as more troops suffer the aftereffects of the Iranian ballistic missile attack early last month in Iraq.

The department said the latest total is 109 military members who have been treated for mild TBI, a significant increase over the 64 reported a little over a week ago.

The number of injuries has been steadily increasing since the Pentagon began releasing data on the injuries about a week after the Jan. 8 attack at al-Asad Air Base in Iraq.
