A baby has been executed by Islamic State terrorists in the Middle East after its Australian jihadi father tried to flee the war zone and come home.

The Australian infant, whose gender has not been confirmed, is believed to have been killed in revenge after the child's father contacted authorities in an attempt to escape the conflict in Syria and Iraq, according to the Daily Telegraph.

Authorities would not confirm the baby's age or how the child was killed.

Attorney-General George Brandis said the government condemned "any parent who takes their family to the conflict zone".


"The government has consistently said going to the conflict zone puts yourself and others in danger," he said.

More than 100 Australian terrorists are fighting overseas for terrorist organisations.

The Turnbull government has previously voiced concerns those Australian citizens would try to return home as the Islamic State loses its stronghold.

In an attempt to stop fighters from fleeing, the Islamic State is believed to control their money and takes their passports, according to the Daily Telegraph.

Security laws to prevent Australian jihads from returning home were introduced by Immigration Minister Peter Dutton in 2015 but several flaws are being reviewed.

The laws were created to strip terrorists with dual-nationality of their Australian citizenship.

So far only one person, extremist Khaled Sharrouf, has lost his Australian citizenship, despite him being reportedly killed two years ago.

Sharrouf gained infamy after his young son was pictured on social media holding a severed human head in 2014.

He went to fight with Islamic State in Syria in 2013 - a year after being released from prison for his role in a terrorism plot.

In 2015, there were unconfirmed reports Sharrouf had died in a drone strike in Mosul.

Other Australians fighting overseas include: senior terrorist Neil Prakash, Sydney jihadi bride Hafsa Mohamed, Hamza El Baf, Perth student Muhammed Sheglabo, Melbourne man Yusuf Mohamed Yusuf and Mostafa Mahamed Farag - who has ties to Al-Qaeda.

Zehra Duman, who moved from Melbourne to Syria to marry Australian jihadist Mahmoud Abdullatif in 2014, is now recruiting wives for jihadis.

Mounir Raad, from Melbourne, is also fighting with extremists overseas.
