11:55 am (IST): Japanese hostage Kenji Goto's mother has once again made an emotional appeal for her son, after begging the ISIS militants last week to spare his life.
This time, Junko Ishido called on Japan's Prime Minister Shinzo Abe to save her son.
"To all members of ISIS, Kenji [Goto] is not the enemy of ISIS. Please release him," she had said last Thursday.
Japanese Prime Minister Shinzo Abe has strongly condemned the new threat by the Islamic State to kill journalist Kenji Goto within 24 hours unless terrorist Sajida al-Rishawi is released by Jordan.
The video was posted online on Tuesday even as Japan and Jordan were working towards a possible resolution of the hostage crisis, as ISIS has also threatened to kill Jordanian pilot Muath al Kasaesbeh, who is likely to be executed before Goto.
"This was an utterly despicable act, and I am appalled. While we are in an extremely severe situation... the government is united to work for the early release of Mr Kenji Goto," Abe said on Wednesday, according to AFP.
The Japanese government convened an emergency Cabinet meeting on Wednesday morning and also stepped up its call for support from Jordan.
"The government, in this extremely severe situation, has been asking for the Jordanian government's cooperation towards the early release of Mr Goto, and this policy remains unchanged," Abe said.
Jordanian authorities were rushing to verify the authenticity of the new video that emerged on Tuesday, in which Goto is seen holding a photo of the pilot who was captured last month.
"Any more delays from the Jordanian government will mean they're responsible for the death of their pilot which will then be followed by mine. I only have 24 hours left to live. And the pilot has even less," the Japanese is heard saying.
Prime Minister Abdullah Ensour said the message in the video did not clarify if the group will also release Kasaesbeh in exchange for al-Rishawi, The Jordan Times reported.
Jordan is reportedly considering a prisoner swap in exchange for the lives of the two ISIS hostages, Japan's Kyodo News Agency had reported on Tuesday.
The Islamic State militants have already purportedly killed Japanese hostage Haruna Yukawa, after Japan refused to cough up the ransom amount of $200 million. While the group has now dropped that demand, they are seeking the release of Iraqi al-Rishawi, who planned a string of bombings in Jordan in 2005 as part of Al Qaeda.
