LOUISVILLE Ky. (WDRB) --  U.S. officials say at least two Americans were killed in Tuesday's terror attack in Brussels.

At this time we do know not the identifies of those people or whether they were killed at the airport or the downtown metro station.

Stephanie Shults from Lexington, and her husband, Justin Shults who is from Tennessee, have been missing since the attack. Stephanie and Justin Shults were at the airport when the bombs exploded.

In a Facebook post, Stephanie's aunt, Betty Newsom, says they "have been 100% assured it is NOT Stephanie Moore Shults or Justin Shults. Keep praying."

Family members are traveling to Brussels to try to find them and get answers.
