Jordan has ramped up its threats to execute a terrorist whom the Islamic State wants set free if the terror group kills its captured pilot, according to a report.

Jordanian officials said would-be bomber Sajida al-Rishawi and other Islamic State fighters would be “quickly judged and sentenced” if Muath al-Kaseasbeh is killed, the Daily Mail reported.

The deadline for a possible prisoner swap passed Thursday with no word from the Islamic State, also known as ISIS, about the fates of al-Kaseasbeh or fellow hostage Kenji Goto of Japan.

“I have reliable contact in the Jordanian government who says a message has been passed to ISIS,” said Elijah Magnier, chief international correspondent for Kuwait’s Al Rai newspaper. “It warns that if they kill the pilot, they will implement the death sentences for Sajida and other ISIS prisoners as soon as possible. There are other prisoners in Jordan that ISIS would like to free.”

Jordan had agreed to an ISIS demand to free al-Rishawi, a would-be al Qaeda suicide bomber. ISIS said that in return, it would spare the life of the 26-year-old pilot, who was captured in December near Raqqa in Syria.

It was not clear from an ISIS recording what would happen to Goto, a freelance journalist, if the deadline was missed. Japanese officials also said they had nothing new to report.

“We are gathering and analyzing information while asking for cooperation from Jordan and other countries, making every effort to free Kenji Goto,” said Japanese Prime Minister Shinzo Abe.

A government spokesman repeated Japan’s “strong trust” in Jordan to help save the journalist.

Yoshihide Suga, the spokesman, said the government had been in close contact with Goto’s wife, Rinko Jogo.

“I fear that this is the last chance for my husband, and we now have only a few hours left,” Jogo said in a statement.
