The fact remains that these brotherly sibling suicide bombers are going to destroy the world with radicalism. From the Boston bombers to the Charlie Hebdo killers and now the Brussel bombers, siblings are getting radicalized.
The two brothers named as the suicide bombers at the center of the Brussels airport and metro attacks this week were listed as a potential terror threat in U.S. databases, NBC News has learned.
According to two U.S. officials, Khalid and Ibrahim El Bakraoui were known to U.S. counter terrorism authorities prior to Tuesday morning.
The officials would not say on which of the many U.S. terrorism databases the brothers were listed. But the disclosure does raise questions about how Belgian authorities could describe them as petty criminals who were not on their counter-terrorism radar.
