Brussels, which suffered through two terrorist bomb attacks this week, needs to ask itself why its Muslim communities feel alienated in that city, an MSNBC terror analyst argued Tuesday.

Evan Kohlmann's remarks came as authorities in Belgium revised the number of civilians murdered in a series of bombings early Tuesday morning upward to 34.

"[T]his is just the beginning, because we have to get to the root causes of why this happened. And those causes have not been dealt with," he said.

"There are international causes and there are local causes. Of course, international cause, there's been a war going on in Syria and Iraq now for going on five years. And that war, in addition to killing hundreds of thousands of Syrians, is now coming in the form of blowback to us here in the west. The second issue is more local concerns, right?" he asked.

He then pivoted to the point that analysts must also investigate the issue of terrorism on a local level.

"Why is it that Muslims and other immigrants in Belgian have such problem integrating with local society? Why is it that they do not feel like they are Belgian? Why is it that they are ghettoized into these communities?" he asked.

"And that has a lot to do with what's going on here. Because, again, if you look at the numbers, way – a much higher percentage of Belgians have gone to go fight in Iraq and Syria than French nationals, and it's right next door. What is the reason for that discrepancy?" he added.

The Islamic State has taken credit for the Belgium Bombings.
