USA counterterrorism officials are saying they're working to get more information on the supposed new leader of ISIS.
The United States is looking into the new leader of the Islamic State in Iraq and Syria (ISIS) to determine his role in the organisation and where he came from after a USA raid last month killed its former leader Abu Bakr al-Baghdadi, Nathan Sales, the U.S. counter-terrorism coordinator, said on Friday (Nov 1).
But while USA intelligence agencies have been examining Thursday's audio message, officials have yet to make a public determination about al-Qurashi's real identity. Al-Qurayshi's nationality is not known.
But for now, analysts say IS will likely try to keep the new leader's true identity a mystery for as long as possible.
Under Baghdadi, Daesh spread over wide segments of Iraq and Syria beginning in 2013, eventually claiming the formation of a "caliphate" in the region as it plotted and carried out gruesome attacks that reached far beyond its main territorial bastion.
The terrorist organization needed a new leader after the assassination of the former one - Abu Bakr al-Baghdadi.
"From a security perspective, it makes sense for them to be careful", according to Aaron Zelin, a fellow at the Washington Institute for Near East Policy, noting that for years after he took over, Baghdadi's actual identity was in doubt.
The group said a successor to Baghdadi identified as Abu Ibrahim al-Hashemi al-Quraishi had been appointed.
Baghdadi, who led IS since 2014 and was the world's most wanted man, died in a USA special forces raid in Syria's northwestern province of Idlib on Sunday.
"We know the successors", he said at the time.
The organization also suffered a second defeat after the abolition of Abu Hassan al-Muhajir, an ID spokesman who would nearly certainly have taken the lead.
President Donald Trump on Tuesday said that al-Muhajir, a Saudi Arabian national, had been "terminated by American troops" in a separate operation. "And we already have them in our sights".
