Greater Christchurch mosque shootings
Quick Summary
The Christchurch mosque shootings occurred on March 15, 2019, when an Australian white supremacist attacked two mosques in Greater Christchurch, New Zealand, during Friday prayers. The assailant killed 51 people and injured dozens more. This event was characterized as a terrorist attack by Prime Minister Jacinda Ardern, marking one of the darkest days in New Zealand's history.12
In response, New Zealand banned military-style semi-automatic rifles, tightened gun dealer regulations, and established a national firearms registry. This incident was the worst mass shooting in modern New Zealand history, surpassing a 1990 event in Aramoana where 13 people were killed. The attacks prompted significant debate about gun control in a country with a high rate of gun ownership.12
