CNN showed live video of an anti-immigrant protest at the site of a memorial for the terror attack last week in Brussels. Watch here:

"You right now are looking at live pictures from Brussels where anti-immigrant protesters have shown up at the square where a memorial for the victims of the Brussels terrorist attack has been created," says host Jake Tapper.

"Well it's incredible how quickly the mood here changed, Jake," the CNN reporter explained. "Just about half an hour ago this was a very quiet reverent scene. People were passing through the square, lighting candles, laying flowers, remembering the dead. It's Easter Sunday so a lot of people took the time to come here to memorialize the dead.

"And then suddenly essentially what we saw was a march, a far white wing fringe group associated with football or soccer hooligans who marched on the square, a few hundred of them, chanting very loudly and very aggressively anti-immigrant chants ... 'this is our home,' or 'we're in our home' and then you could hear other people in the crowd chanting back 'we are all the sons of immigrants.' It become this dualing chants but things did get quite tense quite quickly. We saw a number of people doing nazi salutes. You can see behind me how the police just completely locked down the square in a matter of minutes."
