Saudi national Abu Abdel Rahman was killed by an unknown gunman in besieged Mosul, the terror group's northern Iraqi stronghold, according to a security source.
There have been numerous reports in the last year that he has either been killed or injured - but none have yet been confirmed.
It comes amid separate reports an ISIS commander in charge of executing women has been assassinated in Iraq.
Saudi national Abu Abdel Rahman was killed by an unknown gunman in besieged Mosul, the terror group's northern Iraqi stronghold, according to a security source.
The fanatic, who oversaw the execution of women in the city, is understood to have been killed 'right on the spot'.
According to IB Times, the security source said: 'The unknown gunmen shot at Abu Abdel Rahman, Isis' senior commander, in al-Askari region in the centre of Mosul city, and he was killed right on the spot.'
It comes a day after it emerged that a British sniper in Iraq killed three ISIS terrorists with one bullet in what has been described as a shot in a million.
The SAS marksman fired one bullet that killed two men instantly before it ricocheted into a third during a November mission in a remote northern Iraqi village.
The sniper fired his single .338 Lapua Magnum bullet from a L115A sniper rifle from a range of 1,800m just as the senior ISIS members prepared to fire shots into a crowd of women and children.
News of Rahman's assassination emerged as Iraqi forces retook two areas from ISIS in Mosul, sealing their control of the east bank three months into an offensive to reclaim the city.
And it comes as Ankara claimed 65 ISIS fighters had been killed by the Turkish army in northern Syria yesterday.
Turkey launched an operation to drive the jihadists away from the Syrian border five months ago and have been besieging ISIS controlled town of al-Bab for weeks.
In Mosul, Iraqi forces have recaptured 'Al-Milayeen neighbourhood and Al-Binaa al-Jahiz area and raised the Iraqi flag over the buildings', the military said in a statement. 'These are the last neighbourhoods of the centre of the city (on) the left bank,' the statement said, referring to eastern Mosul.
It also said that federal forces had retaken control of the road linking Mosul, Iraq's second city, to Dohuk, a provincial capital in the west of the autonomous region of Kurdistan...
