William and Kate, The Duke and Duchess of Cambridge, and Harry and Meghan, The Duke and Duchess of Sussex, have said they have all spent time in Christchurch and its "open-hearted and generous" people.
They condemned the violence on the Muslim community, calling it "horrifying assault on a way of life that embodies decency, community, and friendship."
"No person should ever have to fear attending a sacred place of worship," the royal couples said in a statement.
Here's the full statement:
Our hearts go out to the families and friends of the people who lost their lives in the devastating attack in Christchurch.
We have all been fortunate to spend time in Christchurch and have felt the warm, open-hearted and generous spirit that is core to its remarkable people.
No person should ever have to fear attending a sacred place of worship.
This senseless attack is an affront to the people of Christchurch and New Zealand, and the broader Muslim community. It is a horrifying assault on a way of life that embodies decency, community, and friendship.
We know that from this devastation and deep mourning, the people of New Zealand will unite to show that such evil can never defeat compassion and tolerance.
We send our thoughts and prayers to everyone in New Zealand today.
