Junko Ishido, mother of hostage Kenji Goto, has urged ISIS to spare the life of her son. 

"To all members of ISIS, Kenji [Goto] is not the enemy of ISIS. Please release him," she said on Thursday. 

"I sincerely apologise to the Japanese government and all concerned foreign countries for all the trouble that my son has caused. I have been just crying for last three days, filled with sadness. Words fail to describe how I feel. Kenji always has been a kind person ever since he was little. He was always saying, 'I want to save the lives of children in war zones," she said, according to CNN

The 72-hour deadline set by the Islamic State to save the lives of the two Japanese hostages it has held will expire in a few hours on Friday.

The deadline expires at 2.50 pm Friday, Tokyo time (12:50 a.m. ET). Japanese Chief Cabinet Secretary Yoshihide Suga said that no contact was established till Thursday. 

ISIS had demanded a whopping $200 million in exchange for the lives of Kenji Goto and Haruna Yukawa, who otherwise are expected to meet the same fate as several American and British hostages have in the past months.

However, it is not yet clear if Japan will pay the ransom amount to the terror group. Japan seems to be stuck in a Catch-22 situation, experts believe as the country was part of a G8 communique in 2013, which said that the nations "unequivocally reject the payment of ransoms to terrorists", according to CBC.
