New Zealand mosque gunman Brenton Tarrant who shot and massacre 51 people at two mosques in Christchurch on March 15 last year has been sentenced to life imprisonment without parole Thursday.

Brenton Tarrant, a 29-year-old Australian, rampaged Muslim worshipers at the Al Noor Mosque and Linwood Islamic Center in Christchurch for 20 minutes during prayers, which he live-streamed on Facebook.

He had handed 51 charges of murder, 40 charges of attempted murder and a charge of committing a terrorist attack.

It is the first time such charges have been handed down in New Zealand history.

High Court Judge Cameron Mander called on Thursday, his actions “inhuman”, and “brutal”.

“Your crimes are so wicked that even if you are detained until you die it will not exhaust the requirements of punishment and denunciation.”  High court Judge Cameron Mander said on Thursday.

New Zealand doesn't have the death penalty for murder in its judiciary since 1961.
