ISIS STRAP EXPLOSIVE TO FOUR-YEAR-OLD BOY AND BLOW HIM UP A WEEK AFTER THEY EXECUTED HIS FATHER FOR FIGHTING AGAINST THEIR MILITANTS.

ISIS has blown up a four-year-old boy a week after executing his father, who they accused of killing two of its fighters, it has been reported.

The bomb, which was triggered by a remote controlled device, was attached to the boy in a way 'that his organs would be blown apart', a spokesman of the state sponsored rebel group, Popular Mobilisation, is reported to have said.

It comes days after a British boy, Isa Dare, also four, appeared in one of the terror group's sickening execution videos threatening to 'kill kuffar [non believers]'.

The four-year-old boy was killed by ISIS in Iraq's northern al-Shirqat district, Jabar el-Maamouri, a senior official in Popular Mobilisation, told the Alsumaria news agency.

He told human rights organisations of the atrocity to publicise the group's barbarity and 'condemn' the people funding them. 

ISIS is said to have controlled the Al-Shirqat district, considered one of its strongholds, since last June. 

The terror group is also said to have 'wiped out' a village in the Nineveh province after its residents rebelled against the group.

It executed 'dozens of civilians' including old people, women and children in the village of al-Choud, an unnamed source told Alsumaria.

He told of how it carried out mass executions after locals demanded the ISIS gunmen leave the village in peace.

British boy Isa, dubbed 'Jihadi Junior', begged his grandfather to save him just days before he was forced to appear in a sickening ISIS execution video, it emerged today.

The shocking claims come days after a young British boy, Isa Dare (pictured), also four, appeared in one of the terror group's sickening execution videos threatening to 'kill kuffar [non believers]'

The young boy was paraded in military fatigues and an ISIS bandanna while being made to declare: 'We are going to kill the kaffir (non-believers) over there.'

He was brainwashed by ISIS fanatics after being taken to Syria three years ago by his mother, the Muslim convert Grace 'Khadija' Dare, 24, who had links to the killers of Lee Rigby.

His grandfather, Henry Dare, 59, said Isa made a desperate plea for help during a heartbreaking phone call just days before he featured in the barbaric stunt, saying: 'Please save me.'
