A captured ISIS fighter has revealed that the terror group planned to exploit the flow of immigrants through the Mexico border to enter into the United States and carry out attacks to cripple the economy.

Abu Henricki, a Canadian with dual Trinidadian citizenship, who was detained by the SDF in Rojava, Syria, said he and other Trinidadians were ‘invited to attempt to penetrate the US borders’ to mount financial attacks on the United States.

Henricki told researchers from the International Centre for the Study of Violent Extremism (ICSVE): “Emni (the ISIS intelligence arm) was inviting us.” He said the Emni member who invited him was probably a Tunisian. “He approached the guys and they approached me. He didn’t come directly to me.”

The ISIS fighter explained they wanted to do "financial attacks" to cripple the U.S. economy. “Apparently, they have the contacts or whatever papers they can get to a false ID, false passports to send me out for this kind of attack. They have their system of doing it. So that’s may be the way that I could have gone out with other individuals.”

Henricki said they were planning to send him to Puerto Rico and from Puerto Rico to Mexico. “All this was masterminded by a guy in America. Where he is, I do not know. That information, the plan came from someone from the New Jersey state of America,” he said.

He told the researchers that he was asked to go to the U.S. in 2016 as he was from that area. However, he refused and was put into prison and tortured. “They beat me a lot. I was suspended from the back, standing on my toes, given no food for a few days, waterboarded while blindfolded, and they put a bag over my head.” Henricki said he was released after they found nothing on him.

He revealed that he had been contacted by two organizations from the U.S. and Canada to help stop foreign attacks. “This one guy in Canada wants to take me under his wing. Another one (the U.S. intelligence) wants me to go around to people I met, Americans from Texas.”

The captured fighter also gave information about a Abu Adam, a Bengali-American and his two cousins from New York. “One was American but Turkish --Abu Ilias. He was from Texas. He was killed in Baghouz in a drone strike,” Henricki said.
