FBI Director James Comey says the agency has so far found no connections between the terrorists behind the Brussels attacks and anyone in the United States, NBC News reported.

Comey said whenever there's a terrorist attack overseas, the FBI pays extra attention to terror suspects in the US, looking for any signs of copycat attacks. And agents look for any kind of connections — communications, family relationships and so on — with people in the US.

So far, he says, there is no sign of either in the case of the Brussels attacks.
