A radio station affiliated with Islamic State reported that the jihadist army shot down a fighter jet in the southern part of Baghdad and captured its pilot, just days after it showed a captured Jordanian pilot in Syria.

The report did not specify if the plane was part of the U.S.-led coalition the Iraqi military, nor did it reveal the pilot’s identity. The Iraqi military stated that none of its warplanes were downed in the area.

The uncorroborated claim comes days after Islamic State announced downing a coalition warplane and taking its Jordanian pilot hostage following an air raid near Raqqa, Syria, the Islamic State’s self-proclaimed capitol.

Jordanian authorities confirmed the capture of the pilot but the U.S. military said there was no evidence suggesting the terror group did in fact shoot down the aircraft. Analysts warn about taking any Islamic State claims at face value without substantial evidence.

“The Jordanian pilot they claimed to “shoot down” was in fact not shot down but a pilot who crashed,” said KT MacFarland, a Fox News national security analyst.

In yet another claim, Islamic State released a video on Monday in which it claimed to have downed an Iranian-made drone in the al-Diyala province in eastern Iraq. The footage shows several masked armed militants with what resembles an unmanned aircraft in the background.

If true, the downing of Iraqi, Iranian or coalition aircraft would be a major win for Islamic State, according to McFarland.

“ISIS will use that as a major propaganda coup,” McFarland said.
