Islamic State group supporters are reportedly plotting to kill Christians with chainsaws at a shopping center in Belgium, according to a teenage boy under investigation in Belgium for threatening to murder Christians. The terror plot underscores the militant group's ongoing war on Christians and other people of faith, including Muslims who do not accept its violent beliefs.  

Supporters of the militant group also known as ISIS have carried out lone wolf attacks in the United States, France, Belgium and other nations in recent months, but it's unclear whether the chainsaw massacre plot is a serious threat. British tabloids reported Friday that the teenager boy is the son of a radical Imam in the eastern Belgian city of Verviers. He was reportedly arrested after he called for the murder of Christians while down the street. He told police about the chainsaw plot while being questioned. 

The boy was not named. His father is known as Shayh Alami, who has reportedly told investigators in recent months that Belgium is a main target for terror attacks carried out by ISIS supporters. 

Theo Francken, the Belgian Secretary of State for Asylum and Migration, told the Daily Mail the "hate Imam" could soon be deported from Belgium. "I already signed the order to remove the Imam from Belgian soil. But he appealed the decision, so I can only hope for a quick sentence. Clearly radicalism runs in the family," Francken said. 

ISIS executioners have used chainsaws in the past to kill victims. They are also known for carrying out other violent murders. ISIS fighters executed 21 Coptic Christians from Egypt in February 2015 on a Libyan beach. A video of the captives wearing orange jumpsuits as they were killed made international news for its brutal images.

In March, ISIS claimed responsibility for coordinated terrorist attacks that killed 31 people and injured 300 more in Brussels.
