Jordanian hostage Moaz al-Kasasbeh 'killed by IS'
A video published online by Islamic State militants claims to show Jordanian hostage Moaz al-Kasasbeh being burned alive.
The video, which could not immediately be verified, showed a man standing in a cage and engulfed in flames.
He was captured when his plane came down near Raqqa, Syria, in December 2014.
