However, the particulars of the terror chief’s death are not yet clear.
In his last speech in May, he urged lone wolves to carry out atrocities across Europe and during Ramadan in the US.
He said: “Ramadan, the month of conquest and jihad. Get prepared, be ready to make it a month of calamity everywhere for the non-believers.”
He’s wanted by the United States who put a £5million bounty on his head in 2014.
Terror analyst Rita Katz, from the SITE Intelligence Group, described his death as a “major blow” for the terror group.
She said: “When calling for lone wolf attacks in [the] West, ISIS fighters/supporters quote Adnani more than any other individual.”
