ISIS have reportedly killed 45 of their own fighters by locking inside a forensic freezer after they attempted to flee during a battle in Iraq.

The staggering claims were made by the Iraqi media agency Al Sumaria News, who reported that the victims were shut in the freezers for a whole day.

After their agonising deaths, the bodies of the victims were allegedly stretched out along the sides of the road to act as a warning to any other ISIS defectors, according to the Daily Mirror.

The claims come as at least 12 people were killed in two separate car bomb attacks in Baghdad targeting security forces, police sources said today.

There was no immediate claim of responsibility for the blasts which wounded a further 39 people, but ISIS regularly carries out attacks in the Iraqi capital, including one on Friday at a Shi'ite mosque.

The larger of Saturday's bombs hit a security checkpoint in the northern al-Husseiniya district, killing nine.

The second targeted an army convoy in Arab al-Jabour, an area of date palm groves on Baghdad's southern outskirts.

ISIS have developed a reputation for their indiscriminate brutality against prisoners, civilians and even their own fighters

Security has gradually improved in Baghdad, but bomb attacks against the security forces and Shi'ite residential or commercial areas are still a regular occurrence

The Iraqi government has retaken several major cities from Islamic State in the past year and slowly pushed the militants back towards the Syrian border.
