An Islamic State fighter who speaks with a British accent warns the US it is now fighting an "Islamic army" before apparently beheading US journalist James Foley.
The militant accuses the US of being at the "forefront of aggression towards the Islamic State".
He warns President Obama any attempts to "deny Muslims their rights of living in safety under the Islamic caliphate will result in the bloodshed of your people.”
"You're no longer fighting an insurgency. We are an Islamic army," he says.
