Mourners gathered over the weekend in New Zealand and around the world to pay tribute to the victims of Friday’s deadly terrorist massacre at two mosques in Christchurch, New Zealand. The death toll has reached 50, with at least 50 people injured. Police have arrested and charged 28-year-old Australian Brenton Tarrant, who they say acted as a lone gunman and is described as a right-wing, anti-immigrant white supremacist. Tarrant live-streamed the attack and published a manifesto in which he praised President Donald Trump as “a symbol of renewed white identity and common purpose.”

In the wake of the horrific attack, the deadliest shooting in New Zealand’s history, Prime Minister Jacinda Ardern vowed to reform the country’s gun laws.

Prime Minister Jacinda Ardern: “We cannot be deterred from the work that we need to do on our gun laws in New Zealand. They need to change. Regardless of what activity may or may not have happened with gun retailers, they will change.”
