BBC News on September 3, 2014, reported that an Islamic State video purporting to show the beheading of US hostage Steven Sotloff has sparked outrage. Excerpts below:
The US is still trying to verify the video but said the killing if confirmed would be one of “sickening brutality”.
His family said they were “grieving privately”. Mr Sotloff, 31, was seized in Syria in 2013. He appeared in a video last month which showed fellow US journalist James Foley being killed.
A militant in the latest video also threatens to kill a British hostage, who is shown in the footage.
The family of the British hostage have asked the media not to release his name.
The militant has a voice with a British accent similar to that of the man who appeared to carry out the beheading of James Foley.
The timing of the latest video cannot be confirmed
After the news of the video emerged, US President Barack Obama ordered the deployment of another 350 troops to Baghdad to protect US diplomatic facilities.
The US has launched more than 120 air strikes in the past month to try to help Kurdish forces curb the IS advance.
