More On Iraq

The U.S. and Britain vowed to hold accountable those responsible for an attack in Iraq that killed three troops.

Gunnery Sgt. Diego D. Pongo of Simi Valley, California, and Capt. Moises A. Navas of Germantown, Maryland, died Sunday.

It's the first deadly hostile incident for U.S. service members this year in the fight against ISIS in Iraq and Syria.

The size of the Iranian missiles is to blame for the increased number of troops diagnosed with TBI, a Pentagon official said.

The latest figures represent a dramatic increase from the last Pentagon injury report.

The U.S. has yet to receive assurances from Baghdad that the Patriot would be allowed into the country.

More than 60 troops who suffered TBI from the Iranian missile strikes are likely to be approved for Purple Hearts.

The DoD's reporting of the incident has come under scrutiny as officials initially said there were no casualties.

Whether the troops could receive the Purple Heart for injuries as a result of enemy action is under review.

Despite early reports that no Americans were harmed, 11 U.S. service members did sustain injuries.
