A former Army ranger who was a U.S. aid worker in Syria is reportedly dead, after the Islamic State released yet another video claiming to have beheaded Peter Kessig.

The Associated Press reported that this video was different in a number of ways.

First, the video did not start with targeting a leader, such as President Barack Obama or Prime Minister David Cameron, but instead showed the beheading of a dozen Syrian soldiers.

Second, while in the past the alleged ISIS militant has had a distinct British accent, the voice in this new video has been distorted.

The FBI and other authorities previously said they have been able to identify the individual in the first several videos, but have not publicly released his identity.

Third, the video did not show an actual beheading, nor did it end with the threat to behead anyone else.

The final difference is a location has been given in the video. The militants identified their location as Dabiq, a town in northern Syria.

ISIS has used the town name to title its English-language propaganda magazine, because it believes that the town is where there will be an upcoming epic battle between Muslims and their enemies.

U.S. officials are working to verify the authenticity of the video, and the Kassig family is awaiting the results.

"We prefer our son is written about and remembered for his important work and the love he shared with friends and family, not in the manner the hostage takers would use to manipulate Americans and further their cause," the family said in a statement, according to AP.

The new video speaks to the U.S. presence in Iraq to fight ISIS. Specifically, the militant said that Obama claimed to have pulled out of Iraq, but with the air strikes and that some troops having been sent to the region, it is all a lie.

"Rather, you hid some of your forces behind your proxies," the militant said, according to AP.
