The Islamic State group said on Thursday it was holding an Israeli Arab who had posed as a foreign fighter in order to spy for Mossad, an account denied by Israel and by the man's family, who said he had been kidnapped.
In an interview published by Islamic State's online English-language magazine Dabiq, Muhammad Musallam, 19, said he had joined the insurgent group in Syria so as to report to the Israelis on its weapons caches, bases and Palestinian recruits.
After his conduct aroused the suspicion of Islamic State commanders, Musallam was quoted as saying, he broke cover by phoning his father in East Jerusalem, leading to his capture.
