It comes two days after Japan’s Prime Minister Shinzo Abe pledged $200million in non-military support for countries fighting ISIS in Iraq and Syria.

The video, identified as being made by the group’s al-Furqan media arm and posted on militant websites associated with the extremist group, mirrored other hostage threats it has made. 

The clip, posted on militant websites associated with the extremist group, featured the British-accented militant widely known as ‘Jihadi John’ who appeared in the beheading videos of four Western hostages last year.

It shows the two Japanese captives in orange jumpsuits that the militants identify as journalist Kenji Goto Jogo and military company operator Haruna Yukawa.
