(CNN) —  

Fifty people were killed and 50 others wounded in a terror attack on two mosques in Christchurch, New Zealand, police announced Sunday.

The unprecedented mass shootings were carefully planned, and have shocked the usually peaceful nation

New Zealand Prime Minister Jacinda Ardern described the attack on Friday as one of her country’s “darkest days.” She said that the suspects held “extremist views” that have no place in New Zealand or anywhere else in the world.
