The father of a Jordanian pilot captured by Isis after his plane crashed pleaded for his son's release, as reports emerged that the jihadists were preparing to publicly execute him.
First Lieutenant Maaz al-Kaseasbeh was captured after his warplane crashed over the Isis "capital", Raqqa, while carrying out air strikesagainst the militant group.
Isis claimed to have shot down the plane with an anti-aircraft missile - but the US later said "evidence clearly indicates" this was not the case.
It was the first warplane lost and the first capture of a serviceman since the coalition started strikes against Isis in Syria in September.
Kaseasbeh's father, Safi Yousef al-Kaseasbeh, speaking in the Jordanian capital Amman, urged the militants to remember that his 26-year-old son was a Muslim.
Isis jihadists sought to turn the event into a propaganda coup, publishing photographs on pro-Isis websites, showing its fighters holding the captured pilot.
One showed Kaseasbeh, wearing only a white shirt, being carried from a body of water by four men.
Another showed him on land, surrounded by about a dozen armed men.
Pro-Isis Twitter accounts published a photo showing a trail of white smoke plummeting to earth and claiming the jet had "suddenly lost altitude" and that they had then hit it with a shoulder-launched missile.
Amaq News Agency, a pro-Isis outlet, identified the village where the Jordanian jet was shot down as Hamrat Ghnam, in the eastern part of Raqqa's countryside.
The US Central Command, which oversees the coalition air war over Iraq and Syria, said: "Evidence clearly indicates that [Isis] did not down the aircraft as the terrorist organisation is claiming."
The statement did not give a cause for the crash, but confirmed the pilot had been taken captive by Isis guerrillas.
