New Zealand Prime Minister Jacinda Ardern said she would seek a change in her country's gun laws after at least one man opened fire during afternoon prayers Friday and killed at least 49 people at two mosques in Christchurch.
"Our gun laws will change," Ardern declared in a news conference Saturday morning local time.
The violent attack struck at the very heart of New Zealand, a country that prides itself on being both peaceful and diverse.
