| Adnani was mostly known for his calls for lone-wolf attacks in the West |
The chief strategist of the Islamic
State group, whose calls for attacks against the West during Ramadan led
to mass bloodshed, has been killed in Syria, IS-affiliated media say.
Reports of his death come as IS is suffering a series of military reverses in both Syria and Iraq. Adnani - who was also the group's spokesman - was "martyred while surveying the operations to repel the military campaigns against Aleppo", Amaq said, without giving details about how he died.
Fighting has escalated around the city in recent weeks, with rebels breaking a siege by government forces and Syrian and Russian warplanes bombing rebel-held areas.

Is besieged Aleppo facing last gasp?
In a statement, Pentagon spokesman Peter Cook described Adnani as the "principal architect of Isil's external operations", using an alternative name for the group.
He had "co-ordinated the movement of Isil fighters, directly encouraged lone-wolf attacks on civilians and members of the military and actively recruited" new members, Mr Cook said.
He added: "We are still assessing the results of the strike, but al-Adnani's removal from the battlefield would mark another significant blow to Isil.'
