The so-called Syrian Observatory for Human Rights said Wednesday that ISIL militants also "took a [non-Syrian] Arab pilot prisoner after shooting his plane down with an anti-aircraft missile near Raqqa city."
The ISIL also released photographs purportedly showing a captured Jordanian pilot on its websites.
Jordanian officials have not made any comment on the incident.
Comment: Jordan has just confirmed that one of their pilots was captured by ISIS.
Later on Wednesday, the Jordanian military confirmed one of its pilots had been captured during coalition airstrikes on IS-held territory. The Jordanian army told IS it is responsible for the pilot's wellbeing.
Jordan, Saudi Arabia, the UAE and Bahrain are among a number of countries that have joined the so-called US-led alliance carrying out airstrikes against ISIL in Syria and Iraq. This comes as most of these countries have been supporting Al-Qaeda-linked militant groups fighting the Syrian government.
If confirmed, this would be the first coalition warplane shot down since the airstrikes started in September.
The ISIL militants, who have seized large swathes of land in Iraq and neighboring Syria, have been carrying out horrific acts of violence, including public decapitations and crucifixions, against all communities such as Shias, Sunnis, Kurds and Christians, in both Arab states.
Comment: Will the incident be used to further the U.S. invasion of Syria?
