New Zealand's Prime Minister Jacinda Ardern has vowed never to say the name of the Christchurch mosque gunman.
"He sought many things from his act of terror, but one was notoriety - that is why you will never hear me mention his name," Ms Ardern said in an emotional address at New Zealand's parliament.
Last Friday's shootings at two mosques left 50 people dead and dozens wounded.
Australian Brenton Tarrant, 28, a self-described white supremacist, has been charged with murder.
The prime minister addressed a special meeting of parliament on Tuesday, opening her speech by using the Arabic greeting "Al-Salaam Alaikum", which in English means "peace be upon you".
She said: "I implore you, speak the names of those who were lost rather than the name of the man who took them. He is a terrorist. He is a criminal. He is an extremist. But he will, when I speak, be nameless."
