CHRISTCHURCH, New Zealand – A Christchurch gun shop on Monday acknowledged selling guns online to the 28-year-old white supremacist accused of killing 50 people in mosque shootings that have upturned New Zealand's reputation as among the world's most tolerant and safe nations. Separately, New Zealand's prime minister Jacinda Ardern said gun law reforms would be announced within 10 days and an inquiry conducted into the country's intelligence and security services which failed to detect the risk from the attacker or his plans.
