ISIS Releases Another Video of Beheading

BEIRUT (AP) — The Islamic State group says it has beheaded another American journalist, in retribution for continued U.S. airstrikes in Iraq.

An internet video posted today purports to show the beading of

by the militant group. He hadn't been seen in Syria since August of last year -- until he appeared in a video released last month by the Islamic State group that showed the beheading of fellow American journalist James Foley.

In the video, the fighter who appears to behead Sotloff says, "I'm back, Obama" -- and says it's because of an "arrogant foreign policy toward the Islamic State." The fighter says, "Just as your missiles continue to strike our people, our knife will continue to strike the necks of your people."

At the end of the video, he threatens to kill a third captive, a British man -- David Haines.

A White House spokesman said he wasn't in a position to confirm the authenticity of the video, and added, "Our thoughts and prayers first and foremost" are with Sotloff's family.

NEW: US family grieving over new beheading video

WASHINGTON (AP) — A family spokesman says relatives of freelance journalist Steven Sotloff are aware of a new video purporting to show his beheading by Islamic State militants.

In a two-sentence statement Tuesday, family spokesman Barak Barfi said Sotloff's family, quote, "knows of this horrific tragedy and is grieving privately."

The family has not been told whether the video is authentic, and Barfi said the family does not plan to make any additional comments now.

Earlier, the State Department said U.S. intelligence officials were still trying to determine if the video was genuine.

Sotloff had been held by the Islamic State since last year.
