KING: Troubling new information just in to CNN. CNN has now learned more than 100 U.S. troops have been diagnosed with mild traumatic brain injuries, that of course in the wake of that January Iranian missile attack on the Al-Assad military base in Iraq. These numbers come from our Pentagon Correspondent Barbara Starr. Barbara, tell us what you're learning.</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: John, we expect the Pentagon this afternoon to announce just that, now over 100 troops diagnosed with traumatic brain injury as a result of the January 8th Iranian ballistic attack on the Al-Assad base in Iraq where these troops were housed. That blast sending a massive wave of blast and shock across the base, causing these traumatic brain injuries. The numbers have only gone up and up since this incident happened. The Pentagon has been struggling to figure out exactly how many. They keep evaluating people, and clearly symptoms are persistent and continuing to emerge more than a month later. Bottom line here, this is a very extraordinary case for the military, to say the least. We have over 100 U.S. troops injured at the hands of the Iranians. That is something that has not happened before, and there is not a clear solution as to how to prevent it again. The Pentagon looking at trying to get Iraqi permission to put patriot missile defenses on those bases. So far that has not happened. Looking to beef up the bunkers, make them stronger that the Americans were sheltered in during this attack. That has not happened yet. We have here, which by any definition with the military would call a mass casualty, a mass injury incident. More than 100 Americans now injured at the hands of this Iranian missile attack. John?</s>KING: Barbara Starr at the Pentagon, Barbara thank you for staying on top of this throughout the past several weeks as the numbers unfortunately climb. Up next for us, we go back to the campaign trail in New Hampshire where Senator Amy Klobuchar says she has a strategy to win.
