His father is a notorious Radical preacher and the founder of the al-Qaeda-supporting Al-Muhajiroun network of extremists in the UK.
Lebanon 24 claimed that his family have refused to confirm or deny the death of his son but said they believed he had been fighting in the province of Homs.
"Also a security source saying that his death could not be confirmed. The source said it could not be ruled out that the reports may be a ruse in an attempt by him to return to Lebanon."
Bakri fled from the UK in the wake of the 5 July 2005 suicide bombings on the London Underground and re-surfaced in Lebanon. Bakri's son is said to have left Tripoli in Lebanon to join ISIS over a year ago.
Radical preacher Omar Bakri Mohammed
His father is currently in Roumieh prison after being convicted of supporting terrorism following his arrest in a raid by security forces in April 2014. Yesterday, he was sentenced to serve an additional six years in prison with hard labour.
One media report claimed that he was fighting under the name 'Abu Ahmed the Lebanese' and was executed by ISIS for 'cursing the prophet Mohammad'.
The article included an image of an Arabic document, dated 29 August, which it claimed was an ISIS statement announcing his execution.
This was due to apostasy - specifically, alleged links to the Turkish and Lebanese governments, which ISIS considers infidels.
It is a ISIS decree, dated August 29, stating Mohammed was sentenced to death for apostasy based on alleged links to the Turkish and Lebanese governments.
