The killings in Christchurch are part of an international pattern of attacks on Muslims, which seem to have increased over the past two years. In January 2017, a man entered a mosque in Quebec City and shot and killed six people. He was sentenced to at least 40 years in prison this year. The killer followed white supremacists, conspiracy theorists and right-wing commentators online, and he was fixated on Muslims and immigrants. He was a fan of President Donald Trump and his Muslim ban.
Since 2016, at least three U.S. mosques have been set afire, and at least three other Islamic institutions across the country have targeted for terrorist attacks.
