abu mosaAbu Mosa, press officer for the terrorist army ISIS, was killed by Syrian military forces this week, the State Department confirmed Aug. 21.

Mosa had a prominent role in a recent Vice News documentary on the Islamic State in Iraq and Syria, taunting the US and claiming that "We will humiliate them everywhere, God willing, and we will raise the flag of Allah in the White House."

The death of Mosa follows ISIS' release of the video execution of American journalist James Foley this week, a propaganda play that reverberated globally.

An ISIS Twitter account said Mosa was killed during "missile clashes" with the Syrian Army at Taqba airbase in the northern party of that country.
