Video Appears to Show Second American Journalist's Execution by Islamic State (Updated)

Video of Steven Sotloff appears online

A new video appears to show the execution of Steven Sotloff, the second American killed by a self-professed member of the Islamist terror group ISIS.

In the video, which appeared online today, Sotloff addresses the camera, saying, "I'm sure you know exactly who I am by now and why I am appearing."

"Obama, your foreign policy of intervention in Iraq was supposed to be for preservation of American lives and interests, so why is it that I am paying the price of your interference with my life?" Sotloff says calmly as the black clad militant holds a knife casually at his side.

Later the video then cuts to the militant who says that as long as U.S. missiles "continue to strike our people, our knife will continue to strike the necks of your people."

The camera cuts again and the militant appears to kill Sotloff.
