Internet Video Purports to Show Sotloff Beheading by VOA News An Internet video uploaded Tuesday by Islamic State purports to show the beheading of U.S. journalist Steven Sotloff. A masked figure in the video also issued a threat against a British hostage, a man the group named as David Haines, and warned governments to back off "this evil alliance of America against the Islamic State," the SITE monitoring service reported. U.S. State Department spokeswoman Jen Psaki said officials are checking into the authenticity of the video. If genuine, Psaki said, "we are sickened." The images follows the video release of the gruesome beheading of U.S. freelance journalist Jim Foley Last month. Officials comment White House spokesman Josh Earnest could not confirm the beheading, but told reporters "our thoughts and prayers" are with Sotloff's family. Sotloff was taken captive in Syria in August 2013, roughly a year after Foley was taken hostage, and worked for Time and Foreign Policy magazines. The video had clear echoes of Foley's murder. Sotloff, as with Foley, appeared in an orange jumpsuit, and his killer is dressed in black, his face hidden. Similar to Foley, Sotloff was forced to kneel in what appears to be a strip of desert before being beheaded. It was unclear when the video was shot. The Islamic State group has seized a large swath of land across eastern Syria and northwestern Iraq, declaring the area a "caliphate." The United States has been conducting airstrikes in coordination with Iraq's government against the group since early August. Amnesty International on Tuesday said it had evidence Islamic State militants are conducting a systematic campaign of ethnic cleansing in northern Iraq, carrying out war crimes, including mass summary killings and abductions. Congressman Ed Royce, Chairman of the House Foreign Affairs Committee, said, "Beheading is a fate that has been perpetrated on many throughout the region by ISIS. What is unique about this is the release of this information -- the way in which ISIS boasts about its ability to kill and terrorize. "We need to form an international coalition to defeat ISIS. They have set up a virtual caliphate on the Internet. We know of over 500 fighters from Britain, many thousands from continental Europe and Asia, an estimated 5,000 foreign fighters streaming in -- getting training by Chechen forces "We in the U.S. should target the terrorist training camps. We should be leading the coalition, using airstrikes and drones," he said. On August 27, Sotloff's mother, Shirley Sotloff, issued a video plea to IS's leader during which she described her son as an "honorable man" who should not be punished for U.S. government actions. "I've learned that Islam teaches that no individual should be held responsible for the sins of others," she said on the video posted on YouTube. "Steven has no control over the actions of the U.S. government. He is an innocent journalist. I've also learned that you, the Caliph, can grant amnesty. I ask you to please release my child."
