CHRISTCHURCH: New Zealand Prime Minister Jacinda Ardern promised on Tuesday that the man responsible for last week's deadly mosque massacres would face 'the full force of the law', as she vowed never to utter his name.

'He sought many things from his act of terror, but one was notoriety -- that is why you will never hear me mention his name,' Ardern said in an emotional address to a special meeting of parliament, which she opened with the Arabic greeting 'as salaam aleikum' -- 'peace be upon you'.
