(Reuters) - New Zealand police on Friday shot and killed a "violent extremist" who was known to authorities, Prime Minister Jacinda Ardern said, after he stabbed and wounded at least six people in a supermarket.

The attacker, a Sri Lankan national who had been in New Zealand for 10 years, was inspired by the Islamic State militant group and was being monitored constantly, Ardern said.
