Demands for revenge against ISIL militants have replaced the criticism levelled at King Abdullah, in response to the brutal killing of a captured Jordanian pilot.
It comes one day after the Islamist group posted a video online purportedly showing Moaz al-Kasasbeh being burnt alive.
The king said “the blood of the martyr Moaz will not be shed in vain” as he pledged a relentless war against the insurgents during a security meeting in Amman.
Kasasbeh was the first member from the US-led coalition known to have been captured and killed by the insurgents.
Unable to bury the fallen pilot, his family held a ceremony in his memory in his home village near Karak where hundreds gathered to pay their condolences.
Jordan is part of the US-led coalition against ISIL and had promised an “earth shaking response” to the killing. However, the government has yet to detail their plans.
