Jordan has vowed to do all it can to secure the release of a pilot captured by Islamic State, after a video was released appearing to show the beheading of a Japanese hostage.

Jordan echoed Japan in strongly condemning the murder of Kenji Goto.

The pilot, Lt Moaz al-Kasasbeh, was captured when his plane came down in December on a mission to support the US-led, anti-IS military coalition.

Jordan says it is willing to exchange an Iraqi prisoner for his safe return.

Government spokesman Mohammed al-Momeni told the official Petra news agency the administration was doing "everything it can to save the life and secure the release of its pilot".

He said: "All state organisations have been mobilised to secure the proof of life that we require so that he can be freed and returned to his home."
