The six-page letter from Brenton Tarrant was posted this week on the website 4chan, which has become notorious as a place for white supremacists to post their views, The Associated Press reported.
And it comes at a sensitive time, with other alleged killers from El Paso to Norway citing Tarrant as an inspiration.
The letter appears to be written in pencil on a small notepad and is addressed to “Alan” in Russia. Much of it appears to be relatively innocuous, discussing a one-month trip Tarrant says he took to Russia in 2015. But the letter also warns a “great conflict” is coming.
