The Republican politician has made controversy his trademark with unflattering pronouncements about most people.
Here people are not particularly surprised that Mr Trump succeeded in offending the people of Brussels on "Mornings with Maria" on the Fox Business Network.
He was being quizzed about his proposal for an entry ban for Muslims travelling to the US and responded:
"There's something going on and it's not good, where they want Sharia law, where they want this, there has to be some assimilation.
There is no assimilation... You go to Brussels, I was in Brussels a long time ago, twenty years ago, so beautiful, and everything was so beautiful. It's like living in a hell hole right now."
