The government has apparently warned that Sajida al-Rishawi and other jailed ISIS commanders would be 'quickly judged and sentenced' in revenge for Muath al-Kaseasbeh's death.
It comes after a deadline for a possible prisoner swap allegedly set by ISIS passed yesterday with no clue over the fate of al-Kaseasbeh or fellow Japanese hostage Kenji Goto.
Elijah Magnier, chief international correspondent for Kuwait's Al Rai newspaper, told MailOnline:
'I have reliable contact in the Jordanian government who says a message has been passed to ISIS.It warns that if they kill the pilot they will implement the death sentences for Sajida and other ISIS prisoners as soon as possible.'
