BERMAN: New this morning, we're now learning that 50 U.S. service members have been diagnosed with traumatic brain injuries following the Iranian missile strike on U.S. forces in Iraq. That is a big jump from the number previously disclosed by the Pentagon, and you will remember, initially, the president said there were no casualties at all. So now the number is 50. CNN's Barbara Starr broke this story. She is live at the Pentagon with the very latest -- Barbara.</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: Good morning, John. Well, what clearly is happening is it is taking some days for symptoms to emerge in many of these troops since the January 8 bombing of the base at al-Assad in Iraq by Iranian ballistic missiles. We are now at 50. There were 16 additional cases that emerged with symptoms and diagnosis since last Friday. It had been 34. Now it's 50. The good news for the troops is that, of the 16, all but one have now been able to return to duty. But look, they have every expectation here at the Pentagon that additional troops still, after all these days, might report symptoms. They are doing medical assessments on about 200 troops that were in that immediate blast area, so there still could be more. END
