Officials believe Najim Laachraoui, suspected of making the bombs used to attack Paris in November, was one of the two suicide bombers in the deadly terror attacks in the Brussels airport, bolstering evidence linking an ISIS terror cell to both attacks, according to NBC News.
U.S. and Belgian intelligence sources said Wednesday they are certain Laachraoui died in blasts at Brussels' airport.
And there are other ties between Paris and Belgium, NBC News has learned.

Brothers Ibrahim and Khalid El Bakraoui, who each took part and separately died in the airport and subway attacks, prosecutors said Wednesday, provided a safe house in Belgium to the terrorists who carried out the carnage in Paris. Some of the bombers met up there before moving on to the French capital. One brother, meanwhile, helped secure weapons and ammunition for the attackers.
Had he not been caught Friday, alleged Paris attacks plotter Salah Abdeslam would have joined in on the Brussels attacks that left at least 31 dead, sources said.
