Attacks by White Extremists Are Growing. So Are Their Connections. - The New York Times
In a manifesto posted online before his attack, the gunman who killed 50 last month in a rampage at two mosques in Christchurch, New Zealand, said he drew inspiration from white extremist terrorism attacks in Norway, the United States, Italy, Sweden and the United Kingdom.
His references to those attacks placed him in an informal global network of white extremists whose violent attacks are occurring with greater frequency in the West.
An analysis by The New York Times of recent terrorism attacks found that at least a third of white extremist killers since 2011 were inspired by others who perpetrated similar attacks, professed a reverence for them or showed an interest in their tactics.
The connections between the killers span continents and highlight how the internet and social media have facilitated the spread of white extremist ideology and violence.
In one instance, a school shooter in New Mexico corresponded with a gunman who attacked a mall in Munich. Altogether, they killed 11 people.
