Some other websites said, '300 Marines Trapped' and '300 Marines Killed.'
Then I found these two, but not much text:

The Islamic State (ISIS) attacked an air base in Anbar, Iraq where U.S. Marines train members of the Iraqi militarys 7th division, according to Reuters. There are more than 300 Marines at the base.
Iraqi soldiers squared off with the militants, and successfully stopped the attack. Coalition forces were several kilometres from the attack and at no stage were they under direct threat from this action," a U.S. defense official told Reuters. Eight members of ISIS were killed during the battle.
Prior to this attack, ISIS has been fighting to keep control of al-Baghdadi, a town in northern Iraq. The United States has led air strikes over the area, including seven strikes between Thursday and Friday mornings. According to the U.S. Central Command, strikes in Iraq hit tactical units of the Islamic State in Tal Afar, Makhmur, Fallujah, Mosul, Kirkurk and al-Asad.

Not exactly a bloodbath on either side, and the Marines training Iraqis isn't new. But... the Iraqis succesfully repelled ISIS. Gotta wonder about the Shia walking in from of a - what - and ISIS storefront?
