In a statement, the army said that Jordanian jet fighters had "destroyed selected targets of the terrorist organization before safely returning to their airbases."
The statement, however, did not say where exactly the ISIL had been struck.
Jordanian fighters carried out similar airstrikes against ISIL targets on Thursday in response to the murder earlier this week of Jordanian air force pilot Moaz al-Kasasba by the militant group.
Jordan's King Abdullah II vowed a "relentless" war on the ISIL after the militant group released a video showing the captured pilot being burnt alive.
Last summer, the ISIL captured large swathes of land in Iraq and Syria, killing thousands of people in the process. It later declared the captured territories to be part of a self-styled "Islamic caliphate."
Since the group captured the northern Iraqi city of Mosul in June of last year, a U.S.-led coalition – which includes Jordan – has carried out numerous airstrikes against ISIL targets in both Iraq and Syria.
