IS Beheading: Militants Threaten Brit Hostage
An Islamic State militant in a video which purports to show the beheading of US journalist Steven Sotloff has warned that a British hostage will be next.
The 31-year-old, from Florida, is seen dressed in an orange jumpsuit in the video - titled A Second Message To America.
Mr Sotloff, who had worked for Time and Foreign Policy magazines, was forced to read out a statement before he was killed.
The US and UK have both said the video showing Mr Sotloff's murder is authentic.
The American freelancer had appeared in a previous video showing the murder of fellow journalist James Foley, in which a masked militant with an English accent threatened him with death unless the US stopped airstrikes targeting IS in Iraq.
The militant is thought to be the same man who murdered Mr Sotloff, according to the US terror video monitoring agency Site.
He then warns that a British hostage - who is shown kneeling at knifepoint - will be targeted next.
"I'm back, Obama, and I'm back because of your arrogant foreign policy towards the Islamic State ... despite our serious warnings."
President Barack Obama, during a news conference in Estonia, said America would "not be intimidated" by Islamic State (IS) violence.
He said: "We will not be intimidated. Their horrific acts only unite us as a country and stiffen our resolve to take the fight against these terrorists.
"Those who make the mistake of harming Americans will learn that we will not forget, our reach is long and that justice will be served."
Hours after the video emerged, Mr Obama authorised a State Department request for 350 extra US military troops to be stationed in Iraq.
The White House said the troops would "protect our diplomatic facilities and personnel in Baghdad".
British Prime Minister David Cameron chaired a meeting of the Government's emergency committee Cobra on Wednesday morning.
During Prime Minister's Questions he said: "All our thoughts are with the British hostage and his family, their ordeal is unimaginable.
"This country will never give in to terrorism. Our opposition to ISIL will continue at home and abroad.
"A country like ours will not be cowed by these barbaric killers."
Foreign Secretary Philip Hammond, speaking after the Cobra meeting in Whitehall, said the Government will examine "every possible option" to protect the British hostage threatened by IS militants.
Sky's Foreign Affairs Editor Sam Kiley watched the video and said: "The killer is holding an identical knife, standing just behind and to the left of Mr Sotloff.
"He is also armed with a shoulder holster identical to the one that carried a pistol on his last video, just prior to the murder of James Foley.
"He has got exactly the same accent... but it is clear that the voice has been somehow treated or adjusted."
Mr Sotloff's relatives said they were aware of "this horrific tragedy" and were "grieving privately". Israel also revealed he had dual citizenship and the country withheld the information to protect him.
Nato leaders are set to attend a summit in Newport, Wales, on Thursday.
