The Japanese government is working to authenticate a video which appears to show the beheading of Kenji Goto, the journalist being held hostage by Islamic State militants.
The US government has said it "strongly condemns" actions by Islamic State militants after a video was posted online appearing to show the execution of Japanese hostage Kenji Goto.
In a statement, the White House called for all remaining hostages to be released and said it was working to confirm the authenticity of the video.
The British sounding Islamist fighter who has become known as 'Jihadi John' appears in the latest unverified video from the Islamic State.
The video, which lasts one minute and seven seconds, took the same format at the previous execution videos, with the hostage Kenji Goto kneeling on the ground before the black-clothed fighter.
Speaking in English, he said:
No mention was made of the Jordanian pilot Mu'adh al-Kasasibah.
The Japanese government is attempting to authenticate a video purporting to show the beheading of Kenji Goto, the Islamic State captive.
SITE Intelligence group said the video features the same killer as previous videos 'Jihad John', killing the kneeling captive.
An online campaign to raise cash for a disabled pensioner has topped £160,000 - smashing the original target of just £500.
The GoFundMepage was set up by Katie Cutler, who took pity on 67-year-old Alan Barnes after hearing of his terror at returning home to Low Fell in Gateshead, Tyne and Wear, where he was badly beaten up in an attempted robbery.
Mr Barnes was born with a number of disabilities, including visual impairments and stunted growth, after his mother contracted German measles during pregnancy.
He was knocked to the ground and threatened in the attack last week, which left him with a broken collar bone.
Ms Cutler set up the page to raise a few hundred pounds to help him in his search for new accommodation - but with donations of up to £1,000 a time flooding in over the past two days, the original target has been beaten many times over.
