Right-wing and racist terrorism is on the rise in the US.

Sputnik – The United States has experienced a considerable increase in hate crimes and acts of terrorism associated with white supremacist and neo-Nazi groups over the past decade.

Following the terrorist attack by a white supremacist against Muslim worshippers in New Zealand on Friday, the US press also pointed to the rise in domestic terrorism perpetrated by racist and nationalist groups in North America, CBS News reported.

In October 2018, a church in Pittsburgh, Pennsylvania, was the target of an attack that killed 11 people. In Charlottesville, Virginia, a rally against nationalist demonstrations ended with three dead after a white supremacist drove his car into the crowd.

Following the incident in New Zealand, mosques across the U.S. had their security reinforced. Although officials and investigators noted that there was no direct threat, the country's security forces stated that right-wing extremism and racially motivated terrorism appear to be on the rise in the United States.

"We are seeing an increase in propaganda," noted New York State's deputy chief of counterterrorism, John Miller.

"[Right-wing hate groups] are borrowing propaganda techniques from other terrorist groups," he added, as quoted by Cbsnews.com.

Attacks by far-right nationalists against immigrants in Europe increased by 43% between 2016 and 2017, while in the US, right-wing extremists were linked to at least 50 murders in 2018, a 35% increase from the previous year, according to CBS News.

"I would say that the biggest culprit is online propaganda. In fact, this morning, after the [New Zealand] attacks, I was seeing celebrations of the attacks online on anti-Muslim hate sites. It's truly disgusting," noted Ibrahim Hooper, spokesman for the Muslim Council of the United States, quoted by MSN.com.

In February of this year, an active-duty Coast Guard lieutenant was arrested after it was discovered that he was stockpiling a large quantity of weapons to initiate what white supremacists call a "race war."

"All these guys are watching," warned Fran Townsend, former White House Homeland Security advisor.

"They observe the reaction, they observe the tactics of those who came before them. And we must recognize that there is a rise in [...] nationalism around the world," she added, as quoted by Cbsnews.com.

The FBI currently estimates it is tracking approximately 900 active domestic terrorism cases, and many are reportedly linked to white supremacists.
