Islamic State (ISIS/ISIL) jihadists in Iraq have reportedly blown up a four-year-old boy with a remote-controlled bomb.

Jabar el-Maamouri, a senior official in the Iraqi state-sponsored Shiite militia movement known as the the Popular Mobilisation Forces, told the Alsumaria news agency that ISIS jihadists detonated “a bomb that was attached to the child through a remote-controlled device so that his organs would be blown apart.”

The vicious execution, which occurred in Iraq’s Al-Shirqat district, came a week after ISIS terrorists killed the boy’s father for allegedly killing two members of the brutal jihadist group at a check point last month, reports The Foreign Desk.

Days prior to the execution, Isa Dare, a four-year-old British boy, appeared in one of ISIS’s execution videos threatening to kill non believers, notes Daily Mail.

Iraq’s Al-Shirqat District reportedly fell under ISIS control in June 2014.

The district “is an important region providing ISIS opponents strategical benefits in trying to push the jihadis out of Mosul and into the north,” points out The Foreign Desk.

ISIS seized large swathes of territory in Iraq and Syria in 2014. The group has become notorious for its brutality, including beheadings, rape, crucifixions, and abductions.

ISIS has imposed strict Islamic law, sharia, in the areas it has conquered.

In June 2015, the UK-based Syrian Observatory for Human Rights (SOHR), which uses a network of ground sources to monitor the conflict in Syria, reported that ISIS crucified two boys for “not fasting” in observance of the Muslim holy month of Ramadan.

During the month of Ramadan, Muslims abstain from eating, drinking, smoking, and having sex until sundown.

ISIS members have also been known to kill fellow jihadists and members of their own family who do not agree with the group’s policies.

SOHR recently highlighted an execution considered brutal even by ISIS standards. A 20-year old ISIS jihadist in the group’s de-facto capital of al-Raqqa shot his own mother in the head before “hundreds of people,” after she had been accused of apostasy.

According to the Syrian activist group Raqqa is Being Slaughtered Silently, ISIS jihadi Ali Saqr al-Qasem shot his mother Lena with an assault rifle.

ISIS has executed tens of thousands of people, including women, children, and its own members who violate their strict laws.

The group’s barbaric actions are carried out by its female members as well.

An ISIS female member in Syria reportedly tortured a 21-year-old woman to death for violating the group’s strict Islamic dress code.
