BEIRUT • The Islamic State in Iraq and Syria (ISIS) has confirmed reports that a senior operative considered the terror group's information minister has been killed.

An ISIS statement on social media on Monday confirmed the "martyrdom" of Abu Mohammad al-Furqan, the nom de guerre of Wa'il Adil Hasan Salman al-Fayad, saying he had been an "emir" of the group's central media body.

Last month the Pentagon said that Fayad, also known as "Dr Wa'il", had been killed in a precision strike on Sept 7 near Raqqa, the Syrian city that is the de facto capital of ISIS.

The air strike had targeted Fayad while he was on a motorcycle outside his house.

Fayad has overseen the group's media production of videos showing torture and executions, said the Pentagon, describing him as one of ISIS' "most senior leaders".

Since it announced a self-styled caliphate across Iraq and Syria in 2014, ISIS has become notorious for broadcasting its macabre tactics.

The group's online network has taken advantage of social media's instant publishing power to circulate footage of mass killings and beheadings.

"The Islamic State's media people are fighters too," said Mr J. M. Berger, co-author of ISIS: The State of Terror and an associate fellow with the International Centre for Counter-Terrorism - The Hague.
