BEIRUT (AFP) - The Islamic State in Iraq and Syria (ISIS) group confirmed on Tuesday the death of British extremist "Jihadi John", saying he was killed in a drone strike in their Syrian stronghold of Raqa in November.

Born Mohammed Emwazi, he was known as the executioner of the militant group, appearing masked in a string of videos showing the beheadings of Western hostages.

In its online magazine Dabiq, the group said Emwazi was killed on Nov 12 "as the car he was in was targeted in a strike by an unmanned drone in the city of Raqa, destroying the car and killing him instantly".

The US military had said at the time that it was "reasonably certain" he had been killed in the strike.
