Reuters reports another journalist beheaded by ISIL

Reuters is reporting that another American journalist, Steven Sotloff, may have been beheaded by ISIL:

The Islamic State released a video purporting to show the beheading of American hostage Steven Sotloff, a monitoring service said on Tuesday, as the militant group raised the stakes in its confrontation with Washington over U.S. air strikes on its fighters in Iraq.

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 said.

"I'm back, Obama, and I'm back because of your arrogant foreign policy towards the Islamic State, because of your insistence on continuing your bombings and ... on Mosul Dam, despite our serious warnings," the man said.

"So just as your missiles continue to strike our people, our knife will continue to strike the necks of your people."

Several news outlets report that Sotloff's family is aware of the video and grieving.

On August 19th, the same group posted a similar video showing the gruesome killing of American journalist James Foley.
