The intelligence community is working to determine if a video purportedly showing the killing of US journalist Steven Sotloff by Islamic State militants is authentic, State Department spokesperson Jen Psaki has told a White House press briefing.

If the video is genuine we are sickened by this brutal act taking the life of another innocent American citizen; our hearts go out to the Sotloff family and we will provide more information as it becomes available.

– Jen Psaki
