Bloodthirsty ISIS terrorists have forced a 12-year-old girl to execute a group of five women by firing squad, it has been reported.
Among those killed was a female doctor who had refused to treat ISIS militants injured in coalition airstrikes.
It is believed to be the first ISIS execution carried out by a young girl, although male members of the group 's 'cubs of the caliphate ' are thought to have killed prisoners in the pastThe massacre occurred in Nineveh Province, in northern Iraq yesterday, Alsumaria News reported.
A source said: 'This evening, a 12-year-old girl belonging to the so-called ISIS executed five women, including a doctor who refused to medicate ISIS members that were wounded in a coalition bombardment, by firing squad.
The terror group routinely posts propaganda videos showing its so-called youth brigades undergoing military training.
ISIS boasts about these vile training academies through its social media channels, referring to its young recruits as the 'cubs of the caliphate '.
It also shows them off as 'martyrs ' when young recruits perish on the battlefield or in sickening suicide attacks which they are brainwashed into believing are a 'great honour '.
In some instances, it releases videos which it claims shows the youngsters carrying out executions.
Last month a video emerged purporting to show an 11-year-old boy kneeling down to kiss his father 's hand before blowing himself up in a truck laden with explosives.
Footage of the child jihadi, identified as Abu Imara al Omri, was posted online in January by ISIS supporters, who claimed the boy was used to help take the village of Ghazl near Aleppo, Syria from forces loyal to president Bashar al-Assad.
