"We thank him for his extraordinary bravery," the Prime Minister said.

"It says a lot about the nature of humanity at a time when we are facing difficult issues that someone who is not a citizen of this country stood bravely at the top of those escalators and stopped this perpetrator from getting onto another floor and potentially inflicting further carnage on citizens."
