Jordan has vowed to do all it can to secure the release of a pilot captured by the Islamic State group, after a video was released appearing to show the beheading of a second Japanese hostage.
A Jordanian government spokesperson says Jordan is still ready to hand over a jailed Iraqi militant to the IS in return for the airman Muath al-Kaseasbeh.
The pilot's father, Safi al-Kaseasbeh, says the government is working on his son's release.
"The National committee has repeated its demands to the Jordanian government and asked for more efforts and for the opening of a dialogue channel with the Islamic State militants, be it through public figures, NGO'S or through international efforts in the region."
He was speaking a day after a video emerged purportedly showing the militants beheading Japanese hostage Kenji Goto.
The video made no mention of the Jordanian pilot, raising fears for his life.
The IS had demanded the release of Sajida al-Rishawi, an al-Qaida prisoner, by Thursday or the pilot would be killed.
The deadline passed after Jordan said it could not free her without proof the pilot was alive.
Jordan and Japan have reportedly conducted indirect negotiations with the militants through Iraqi tribal leaders, but late on Friday Japan's Deputy Foreign Minister reported a deadlock in those efforts.
So far Japan's envoy to Amman for the hostage crisis has refused to comment on details of what went wrong.
