Michael Ross, 24, was also there.
"We didn't understand if the parade would continue or not. Some people left the area, but most of us stayed," he says.
"We started to think if it's going to be cancelled we will stay and we will scream and shout that we are not giving up."
He feels it was really important that the event carried on.
"It was very symbolic that when we continued walking the road was full of blood, full of blood and medical equipment that was left there.
"It was definitely a crazy moment. I felt like we still fight for something. We still fight for our safety and security."
