Japanese hostage killed?: Video emerges showing hostage holding picture of fellow captive's body

Could this be for real?

The Japanese government has made a defiant attack on ISIS after the release of a new audio recording purporting to be from one of the hostages pictured with terrorist Jihadi John.

In the recording, a voice claiming to be that of Kenji Goto, 47, one of the Japanese men who appeared in the terror group's latest video, says his fellow captive, Haruna Yukawa, has been killed.

He blames the death on Japanese Prime Minister Shinzo Abe, and says he will be killed as well if ISIS's new demand to release a failed female suicide bomber is not met. 

Speaking today, Mr Abe condemned the video, branding it 'outrageous and unacceptable', but said his government 'will not give in to terrorism'.  

The Japanese government said cannot verify its authenticity after allegations that the Jihadi John video was also stitched together from several recordings. 

Japanese chief cabinet secretary Yoshihide Suga said cabinet ministers were holding an emergency meeting about the new message.
