Attacks by White Extremists Are Growing. So Are Their Connections

 and SIMONE LANDON, New York Times, APRIL 3, 2019

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.

Many White Extremist Killers Were Inspired by Earlier Attacks

One object of fascination for the Christchurch killer and at least four other white extremists was Anders Behring Breivik, the far-right extremist who killed 77 in a bombing and mass shooting in Norway in 2011.

Mr. Breivik’s lengthy manifesto offered a litany of grievances about immigration and Islam — and the attacks became a model for future ones.

“I think that Breivik was a turning point, because he was sort of a proof of concept as to how much an individual actor could accomplish,” said J.M. Berger, author of the book “Extremism” and a research fellow with VOX-Pol, a European academic initiative to study online extremism.

“He killed so many people at one time operating by himself, it really set a new bar for what one person can do.”

Mr. Breivik was not the only mass killer to inspire copycats. The Christchurch shooter also paid tribute to a Canadian man who opened fire inside a Quebec City mosque in 2017, writing his name on one of the guns used in his attack.

That Canadian gunman read extensively about Dylann Roof, the American who killed nine worshipers at a black church in South Carolina in 2015.

At least four white extremist killers made statements online praising Elliot Rodger, a racist and misogynist who targeted women in a 2014 spree, before carrying out their own attacks.

All these attacks occurred amid a surge of white supremacist and xenophobic terrorism in the West that has frequently targeted Muslims, immigrants and other minority groups, the Times analysis found.

The Rise in White Extremist Terrorism Attacks

In Europe, North America and Australia

in Europe.

The analysis was based on data from the Global Terrorism Database and identified nearly 350 white extremist terrorism attacks in Europe, North America and Australia from 2011 through 2017, the latest year of available data. We also examined preliminary data on attacks in the United States in 2018.

The database is a project of the National Consortium for the Study of Terrorism and Responses to Terrorism at the University of Maryland. It relies on news reports and other records to capture episodes that meet its definition of terrorism: the use of violence by a non-state actor to attain a political or social goal.

Over this period, white extremism — an umbrella term encompassing white nationalist, white supremacist, neo-Nazi, xenophobic, anti-Muslim and anti-Semitic ideologies — accounted for about 8 percent of all attacks in these regions and about a third of those in the United States.

Erin Miller, who manages the database, said the increase in white extremist terrorism parallels a rise in hate crimes and bias episodes in the West and that deadly attacks are occurring more often.

“There’s a common framing of far-right terrorism or domestic terrorism as being ‘terrorism lite’ and not as serious,” she said. “It’s an interesting question given that far-right attacks can be quite devastating.”

Xenophobia Drives Violence in Europe

In recent years, Europe has seen a surge in far-right and xenophobic violence amid an influx of migrants and refugees from conflicts in the Middle East and Africa.

Retaliation Attacks

Retribution was suspected to be a motivating factor in at least 19 attacks. White extremists responded by attacking mosques after two Muslim men killed a British soldier in 2013. Similar retaliations took place after terrorism attacks on the Charlie Hebdo newspaper by Islamic extremists, and a wave of attacks in Paris in November 2015.

Targeting Muslims
About a quarter of white extremist attacks in Europe targeted Muslims and mosques. These attacks increased significantly starting in 2015 along with a wave of xenophobic violence reacting to the migrant crisis.

Anti-Migrant Attacks Spike

Xenophobia was behind the spike in attacks Europe saw in 2015. At least 86 attacks that year specifically targeted refugee shelters and migrants, and dozens more followed in 2016 and 2017.

2016 Munich Attack
The deadliest of these was a shooting at a Munich mall in 2016. The teenage gunman studied school shooters, admired Adolf Hitler and wrote a manifesto railing against “foreign infiltration.” The police said he most likely planned his rampage for the fifth anniversary of the Norway attacks.

Attacks in North America Are More Deadly

In North America, the ideologies of older white supremacist groups like the Ku Klux Klan have mixed with anti-immigrant and anti-Muslim sentiment and the fresh-faced fascism of the “alt right” to give rise to a more lethal terror.

There were at least 38 attacks that targeted places of worship, like churches, synagogues and mosques across North America.

Mosques and other Islamic institutions

Other places of worship

Until last year, the deadliest of these attacks in the United States were a shooting at a Sikh temple in Wisconsin in 2012 and a shooting at a black church in South Carolina in 2015.

Online Radicalization
An attacker who voiced his hatred of women and people of color in a manifesto before killing six people in California in 2014 signaled a new type of terrorist. The Southern Poverty Law Center, which monitors hate groups, called the attacker the “first alt-right killer.” Several more attackers who fit this profile killed over the next few years.

Rising Violence
Then in 2017, attacks jumped in a tense post-election political environment. Nine of these proved deadly.

Preliminary 2018 data for the United States shows five additional deadly white extremist attacks, including mass shootings at high schools in Florida and Texas and at a Pittsburgh synagogue.
The Global Reach of White Extremism

There were five white extremist attacks in Australia from 2011 through 2017, all of which were attacks on mosques and Islamic centers. There were no such attacks in New Zealand during that same period.

Then the massacre of worshippers at two mosques in Christchurch on March 15 — the deadliest shooting in modern New Zealand history — helped put the global nature of white extremism into relief.

Experts say the same broad motives are at play whether the target is a mosque in Perth or an asylum seekers’ shelter in Dresden or a synagogue in Pittsburgh. Attackers who identify as white, Christian and culturally European see an attack on their privileged position in the West by immigrants, Muslims and other religious and racial minorities.

The difference now is that it is easier than ever for extremists to connect both domestically and across continents, according to Mr. Berger, the “Extremism” author. The entry point for radicalization is less narrow than it was during earlier waves of white supremacist action, when finding ideological fellow travelers typically required meeting in person.

Heidi Beirich, director of the Southern Poverty Law Center’s Intelligence Project, said that given these international connections, it’s important to reconsider the nature of the threat. “We conceive of this problem as being a domestic one,” she said. “But that’s not the case.”

The challenge for law enforcement will be to buck a sometimes myopic focus on Islamic extremism as the only driver of international terrorism.

It may also require rethinking the legal framework for what constitutes terrorism: from violence that arises from a command and control structure to a looser definition that can account for a wider range of violent actors who share a common ideology.

“They don’t see themselves as Americans or Canadians, very much like the Christchurch killer didn’t see himself as an Australian; he saw himself as part of a white collective,” Dr. Beirich said.

“It has never been the case that these people didn’t think in a global way. They may have acted in ways that looked domestic but the thinking was always about building an international white movement.”


This analysis was based on data from the Global Terrorism Database for the years 2011 through 2017 and preliminary data for the United States for 2018. To identify episodes involving white extremists, we looked at the available data on perpetrators; their affiliations with terrorist groups; stated motives and targets; and conducted independent research.

We examined attacks perpetrated by anti-immigrant extremists, anti-Muslim extremists, neo-Nazi extremists, right-wing extremists, anti-Semitic extremists, neo-fascists, white extremists, anti-Arab extremists, the Ku Klux Klan, anti-Sikh extremists and incel extremists. We also examined attacks on migrants and refugees, places of worship and religious figures, and attacks on black people, Hispanic people and Hindus.

For episodes in which the identity of the perpetrator was unknown, we made a determination about ideology based on the target or through further research. We excluded episodes with insufficient evidence of ideological motivation.

We excluded cases that might otherwise have met our criteria — for example, an attack on a mosque — if they took place as part of an active conflict, like in a war zone.

We excluded the small number of instances of right-wing and anti-government political violence in which the perpetrators did not appear to be motivated by white extremist ideology.

Global Terrorism Database researchers mark certain cases as in doubt as to whether they constitute terrorism, but since they were ultimately included in the database, they were included in our analysis when they met our criteria.

Attacks by the same perpetrator that occurred on the same day were counted separately. Location information was not available for two attacks in Europe. These are not shown on the maps but are included in the analysis. The chart showing connections among attackers only includes attacks in the United States and Canada for 2018.
