US President Donald Trump said he did not think white supremacy was growing threat around the world, BBC reported on Saturday.
"I don't really," he said, "I think it's a small group of people with very serious problems."
He added that in New Zealand they were still learning about the massive Friday shooting that claimed the lives of 49 people attending prayer services in two mosques in Christchurch.
Prime Minister of New Zealand Jacinda Ardern said "This is one of New Zealand's darkest days."
The alleged killer is Australian Brenton Tarrant who published a manifesto hours before the shooting in which he said his inspiration was Norwegian terrorist Andres Breivik and that he saw Muslim immigrants as "invaders."
The manifesto was sent to several public figures in New Zealand, including Ardern.
Breivik carried out two terrorist acts in 2011 which claimed the lives of 77 people, he had since claimed to be a fascist and a Nazi.
