A survivor of last year's New Zealand mosque shooting, Hazem Mohammed demanded justice in court on Tuesday.

He and other survivors were facing up to white supremacist Brenton Tarrant, a 29-year-old Australian.

Tarrant is scheduled to be sentenced this week after pleading guilty to 51 murders, 41 attempted murders and one charge of committing a terrorist act during the 2019 shooting rampage in Christchurch which he live-streamed on Facebook.
