A prominent Christian leader of the Chaldean community unveiled the "systematic beheading of children" and other horrendous crimes committed by ISIS. He said that the Sunni extremists are committing genocide against Christians in Iraq and with the aim to instill the Sharia Law as the law of the land.  

In the interview with CNN's Jonathan Mann, Chaldean-American businessman Mark Arabo said that the "world hasn't seen an evil like this for generations." 

"There is a park in Mosul, where [ISIS] they actually beheaded children and put their heads on a stick and have them in the park," he explained. "More children are getting beheaded, mothers are getting raped and killed, and fathers are being hung."

Speaking from San Diego over Skype, Arabo called for the international community to offer asylum to the more than 300,000 Christians fleeing and living in neighboring cities. 

At a meeting in the White House last week, he said the Chaldean-American leaders and the political leaders are saying that the world should come together to stop these crimes against humanity and help alleviate the sufferings of the Iraqi people. 

"The world hasn't seen this kind of atrocity in generations," he said. "This is a crime against humanity. This is much broader than a community or a faith. This is crime against humanity. They are doing the most horrendous, the most heart-breaking crimes that you can think of."

When asked about Sunni extremists' targeting of Christians, Arabo said that around 95 percent of Christians have fled, five percent have converted. Also, the ISIS have marked the death stamps on Christian homes, so whoever returns will get killed. 

"Christian holocaust is in our midst," he said. "This should never be happening in 2014." 

Just last week, the ISIS bombed a church that was 1,800 years old, and have bombed 6 churches so far. 

While France is leading the way in offering asylum, Arabo is calling on the US and the United Nations to recognnize that this is a genocide and do more to address this crisis.   

"This living nightmare is not going away," he said, "but it is only getting worse."

"The world cannot turn a blind eye."
