Jordan is willing to swap an Iraqi woman prisoner involved in a deadly 2005 hotel bombing for a Jordanian pilot captured in December by extremists from the Islamic State group, a government spokesman said Wednesday.
In a statement, Jordan said that the prisoner's release depends on the fate of the pilot.
Such a swap would run counter to Jordan's hard-line approach toward Islamic militants and to the position of its main ally, the United States, not to negotiate with extremists. An exchange also would set a precedent for negotiating with Islamic State group militants who in the past have not publicly demanded prisoner releases.
However, Jordan's government faces domestic pressure to bring the pilot home, while its participation in a U.S.-led military coalition against the Islamic State group is widely unpopular among Jordanians.
The government spokesman, Mohammed al-Momani, did not say whether a swap would actually take place. He also made no mention of Japanese journalist Kenji Goto, who is also being held by the Islamic State group.
Efforts to release the pilot and the journalist gained urgency with the release late Tuesday of a purported online ultimatum claiming the Islamic State group would kill both hostages within 24 hours if the Iraqi woman was not freed.
On Wednesday, al-Momani said that "Jordan is ready to release the Iraqi prisoner, Sajida al-Rishawi, if the Jordanian pilot, Lt. Muath al-Kaseasbeh, is released unharmed." His comments were carried by Jordan's official Petra news agency.
Al-Rishawi was sentenced to death in Jordan for her involvement in a 2005 terrorist attack by al-Qaida on hotels in Amman that killed 60 people. Her release would be a major propaganda coup for the Islamic State group.
Jordan is reportedly in indirect talks with the militants through religious and tribal leaders in Iraq to secure the hostages' release.
The chairman of the foreign affairs committee of Jordan's parliament, Bassam Al-Manasseer, has been quoted as saying that Jordan and Japan would not negotiate directly with the Islamic State group and would not free al-Rishawi for the Japanese hostage only.
Earlier Wednesday, the mother of the Japanese hostage, Kenji Goto, appealed publicly to Japan's premier to save her son.
The mother, Junko Ishido, read to reporters her plea to Prime Minister Shinzo Abe, which she said she sent after both Abe and Japan's main government spokesman declined to meet with her.
"Please save Kenji's life," Ishido said, begging Abe to work with the Jordanian government until the very end to try to save Goto.
"Kenji has only a little time left," she said.
Later Wednesday, a few dozen people gathered in front of the prime minister's official residence, holding banners and placards expressing their hopes for Goto's release.
"I have been trying to keep my hopes up and believe that Mr. Goto will return. I have this faith within me," said Seigo Maeda, a 46-year-old friend of Goto's.
In Jordan, the pilot's father, Safi al-Kaseasbeh, beseeched his government late Tuesday "to meet the demands" of the Islamic State group.
"All people must know, from the head of the regime to everybody else, that the safety of Mu'ath means the stability of Jordan, and the death of Mu'ath means chaos in Jordan," he told The Associated Press.
About 200 of the pilot's relatives protested outside the prime minister's office in Amman, chanting anti-government slogans and urging that it meet the captors' demands.
The militants reportedly have killed one Japanese hostage, Haruna Yukawa, and the crisis has stunned Japan.
Although many in Japan are critical of the two men for going to Syria, Goto's friends and supporters have launched a social media campaign calling for his release.
Tuesday's video resembled a message released over the weekend that purportedly withdrew a demand for $200 million ransom for Goto and Yukawa made in an earlier message.
The Associated Press could not independently verify the videos released Saturday and Tuesday. They lack the logo of the Islamic State group's al-Furqan media arm. But some militant websites affiliated with the Islamic State group referenced the latest video and posted links to it Tuesday.
The latest message condemns Jordan for not releasing al-Rishawi, saying that unless she is freed within 24 hours, the pilot, followed by Goto, will be killed. It says it is the group's last message.
Al-Kaseasbeh, 26, was seized after his Jordanian F-16 crashed near the Islamic State group's de facto capital of Raqqa in December. He is the first foreign military pilot they have captured since a U.S.-led coalition that includes Jordan began an aerial campaign against the Islamic State group in August.
This is the first time that the group has publicly demanded the release of prisoners in exchange for hostages. Previous captives may have been released in exchange for ransom, although the governments involved have refused to confirm any payments were made.
Goto, a freelance journalist, was captured in October in Syria, apparently while trying to rescue Yukawa, 42, who was taken hostage last summer.
The mother of another Jordanian prisoner, Ziad al-Karboli, said her family was told the Islamic State group also wants his release as part of a swap, but it is unclear if that was related to a possible deal involving the Japanese hostage.
Al-Karboli, an aide to a former al-Qaida leader in Iraq, was sentenced to death in 2008 for killing a Jordanian citizen.
