The burning alive of a Jordanian air force pilot by Islamic State terrorists is reverberating throughout the Middle East, a region that has suffered decades of brutal wars.
Jordan executed two Iraqi jihadists, including a woman would-be suicide bomber, yesterday in response to the pilot's killing.
Jordan said it hanged failed suicide bomber Sajida al-Rishawi and al-Qaeda member Ziad al-Karboli before dawn at a prison south of the capital.
Al-Azhar, the Sunni Muslim world's leading religious institution, called for the "killing " of I S terrorists.
Government officials in the region called the immolation of a captive by IS as "barbaric" and "satanic", and warned that similar atrocities are to be expected.
"They wanted to raise the level of ugliness," said Abdulmanam Almushawah, head of a Saudi government programme set up to counter militant Islamic websites.
The airman is the latest captive whose killing has been choreographed and documented by IS. The group says it is punishing countries that joined the US-led military campaign to crush its self-declared caliphate in Iraq and Syria.
The group said it killed two Japanese hostages as retribution for Prime Minister Shinzo Abe's offer of $200-million in non-military aid to states fighting the extremists.
Maaz al-Kassasbeh, 27, was captured by IS in December when his plane crashed in Syria during a bombing run against the group.
His death was captured in a video distributed on Twitter.
Almushawah said Islam prohibits torture, including burning to death.
"The actions of this group have nothing to do with Islam," he said.
IS has killed thousands since setting up its capital in the Syrian city of Raqqah in 2013 and declaring a caliphate the following year.
They shot, beheaded, crucified, stoned and threw those who opposed them from high buildings.
