Elite Iraqi troops battled the ISIS in the streets of Mosul yesterday, as the UN reported jihadists had executed dozens of people inside the city for alleged "treason", 9news Reports.

In Raqqa, ISIS (ISIL, IS, Daesh) has been conducting similar desperate measures, including preparing the deployment of child fighters indoctrinated into the terrorist organisation since birth.

A member of the organisation told the Guardian the child fighters would be used in large numbers not unlike fodder.

“Many of these boys are sons of fighters who have been killed.

They have been programmed like robots.

They fear nothing and are beyond being rescued,” he said.

“All the leaders know what is going on in Mosul.

They are watching the news very closely and have been encouraged by the fact that the Iraqi security forces can’t go any further.

They know how to fight them in the city, and they are confident that they can pin them down for a long time.

Iraqi forces have regrouped after meeting stronger than expected resistance from ISIS on the east bank of the Tigris River running through Mosul after thrusting into the built-up area last week.

Commanders of Iraq's elite Counter-Terrorism Service (CTS) said troops were advancing on two eastern neighbourhoods of the city.
