New Zealand is banning all assault rifles, high-capacity magazines and military-style semi-automatic rifles in response to the nation's deadliest massacre in history, the country's prime minister announced Thursday. Jacinda Ardern said the ban goes into effect immediately and would be followed by legislation next month. New Zealand's citizens should make arrangements to turn in weapons banned under the new laws, Ardern told the nation in a live television announcement. "On March 15, the nation witnessed a terrorist attack that demonstrated the weakness of New Zealand's gun laws," Ardern said. "The guns used in this attack had the power to shoot continuously. The times for the easy availability of these weapons must end. And today, they will." Do you like what you see?
