Tight security as New Zealand mosque gunman sentencing set to begin

The sentencing of an Australian white supremacist, who killed 51 Muslim worshippers in New Zealand -- and live-streamed the massacre -- was set to begin amid tight security in a Christchurch court on Monday. The court building -- where Brenton Tarrant will hear statements from 66 survivors -- was sealed off with large orange barriers as armed police stood guard. The hearing is set down for four days with as survivors and Tarrant, who is representing himself, making submission before High Court judge Cameron Mander hands down a sentence.
