ISIS claims has executed two hostages: Ole Johan Grimsgaard-Ofstad from Norway and Fan Jinghui from China.
They were last seen in an ISIS online magazine called Dabiq in September. Both were being ransomed.
A November issue of the magazine appears to show that both hostages have been executed.
The same magazine also has an article supposedly written by John Cantlie, another hostage. He was last seen alive in a video ISIS released about the Syrian city of Aleppo in February 2015.
