Jordan's army did not disclose what country was targeted during the operation on Thursday, but Al Jazeera has learned that Abdullah told Kassasbeh's father Safi al-Kassasbeh that the fighter jets flying over their town have just returned from Raqqa, the ISIL stronghold in Syria.
"Planes from the Jordanian Royal Forces have just arrived from Raqqa now after bombarding and pounding them," Kassasbeh said after he was given the information by the visiting king.
"God willing we will end their existence in Syria. We ask God to help us annihilate them."
"Jordan's resolve has been stiffened by this tragic murder," Al Jazeera's Nisreen El-Shamayleh, reporting from Karak, said.
"Those who didn't believe ISIL was a threat to the country now say the war against the group is theirs."
On Thursday, Queen Rania also joined Abdullah, paying her respects to the female members of the Kassasbeh family.
