Independent legislator Mazen Al-Dhalaein was quoted as telling the Khaberni website that his son, Mohammed, who went by the name of Abu Baraa, had died in Iraq.
He said he learned of his son's death after seeing his photo on social media accounts linked to Daesh.
Dhalaein said his 23-year-old son had been studying medicine in Ukraine before deciding to join Daesh this summer, traveling to Iraq through Turkey and Syria.
“He considered me and his mother to be apostates and was trying to convince us to join Daesh,” he added.
The MP said he had last heard from Mohammed in August when he sent a message that he “had been signed up for a suicide attack soon”.
In a statement posted on Twitter on Wednesday, Daesh claimed a triple car bombing on the northern outskirts of Ramadi.
Iraqi military sources confirmed suicide attacks in the area Tuesday but were unable to identify the bombers.
