FBI Director James Comey says the agency has found no connection between the terrorists responsible for the Brussels attacks and anyone in the United States, according to NBC News.
Comey said the FBI looks for signs of copycat attacks whenever terrorists strike overseas, with agents looking for any kind of connections, including family relationships and communications, with people in the U.S.
"When people see images of innocent men, women, and children being slaughtered around the world, I hope that will reinforce the notion that the Islamic State, so-called, is not engaged in some heroic, romantic battle on the side of good, but instead they'll see it as a bunch of savages occupying a space that's hell on earth right now."
