Siblings Who Lived in NY Confirmed Killed in Brussels Terror Attacks


New footage has provided a glimpse into the bomb-making safehouse where the Brussels terrorists prepared for their deadly massacre.

Fox News Chief Intelligence Analyst Catherine Herridge said that the apartment was on the top floor, subjecting it to the least amount of traffic.

Also worth noting was that the apartment was virtually unlived-in, suggesting the terrorists lived somewhere else and that this apartment was only part of a larger network.

"It really functioned as a lab for the storing and making of bombs," Herridge said.

Finally, there was an iPad left behind in the apartment that Herridge said was likely a plant with leads to send investigators in the wrong direction.
