On Friday, 15 March morning, a gunman opened fire in Christchurch, New Zealand, killing multiple people in a mass shooting that New Zealand Prime Minister Jacinda Ardern has called "an extraordinary and unprecedented act of violence." He, and reportedly three others, targeted two mosques in the city, killing a total of 49 people and injuring at least 20 others.
One of the gunman, who uploaded a live video of his rampage, has been identified as 28-year-old Australian citizen Brenton Tarrant.
Twitter has taken down his profile, but screenshots remain.
