The House Intelligence Committee chairman believes that Americans were targeted in yesterday's terror attacks in Brussels.
One of the suicide bombers struck at a subway stop near the U.S. Embassy, where some personnel remain unaccounted for.
Meantime, the two terrorists who detonated luggage bombs at the Brussels airport did so near the ticket counters of United, American and Delta Airlines.
Rep. Devin Nunes (R-CA) said "those would be two locations where a lot of Americans can be killed."
Meantime, one of the attackers was deported from Turkey last June and Belgium was warned that he was a suspected ISIS follower.
The terrorist is said to have left a suicide note in a garbage can, stating "I don't know what to do."
He was apparently referring to his likely arrest after the capture of terror ringleader Salah Abdeslam.
