Islamic state media outlet confirms "Jihadi John" is dead.

A media outlet associated with Islamic State on Tuesday released a eulogy for "Jihadi John," a member of the militant group who gained notoriety for his filmed execution of hostages, the monitoring organization SITE reported.

The militant was identified as Mohammed Emwazi, a British citizen of Arab origin. The U.S. military said in November it was "reasonably certain" it had killed him in a drone strike.

Emwazi was described in Islamic State's Dabiq magazine by his nickname "Abu Muharib al-Muhajir.""On Thursday, the 29th of Muharram, 1437 (Nov. 12, 2015), Ab Muhrib finally achieved shahdah (martyrdom) for the cause of Allah, which he had sought for so long, as the car he was in was targeted in a strike by an unmanned drone in the city of Raqqah, destroying the car and killing him instantly," Dabiq said.
