Gen. James Mattis of the U.S. Marine Corps, said his troops have nothing to apologize for, adding, "Let’s not be naive, bad things happen in wars."

We had significant intelligence which caused us to conduct a military operation into the middle of the desert, 85 kilometers south of Husaybah, al Qaim, and 25 kilometers inside from the Syrian border. Relatively barren area. We had a group of people there, not Bedouin. They were -- would appear to have been town dwellers. You saw 4x4s, jewelry. This is one of those routes that we have watched for a long period of time as a place where foreign fighters and smugglers come into this country.

We have consistently talked inside this forum about the foreign fighter flow. This was clearly, in our -- the intelligence that we had suggested that this was a foreign fighter "rat line," as we call them, one of the way stations. We conducted military operations down there last night. The ground force that swept through the objective found a significant amount of material and intelligence which validated that attack. And we are satisfied at this point that the intelligence that led us there was validated by what we found on the ground, and it was not that there was a wedding party going on...

The persons that we had on the ground did not find -- and they were on the ground for an extensive period of time -- they did not find any dead children among the casualties of that engagement...

Obviously, for operational and security reasons, I can't reveal much of the details of what got us there and what we did while we were there. But I am persuaded that, again, the purposes that caused us to conduct that operation in the middle of the barren desert in the early mornings (sic) of the hour, which is kind of an odd time to be having a wedding, against what we believed to be 34 to 35 men and a number of women, less than a handful of women, which doesn't seem to be numbers that one would associate with a wedding, by a group in their four-by- fours, well away from any town, in a known RAT line, which is being used by smugglers and foreign fighters frequently, and other intelligence that we found on the ground, pretty well convinces us that what got us there had a valid purpose...

But we are satisfied that the intelligence that we had, the multiple correlated evidence that got us there, and the actions of our forces on the ground, what they found and what they brought back -- foreign passports, money, weapons, satellite communications -- would be inconsistent with a wedding party for sure, and fairly consistent with what we have seen throughout this country time after time after time, which is the flow of foreign fighters to come in to terrorize and kill the Iraqi citizens.
