Federal authorities foiled an alleged terror plot by an anti-Israel, anti-American extremist group, officials announced on Monday. The group — the Turtle Island Liberation Front — appears to also be one of the organizers of an anti-Israel protest that targeted a Los Angeles synagogue this month. 

Four members of TILF were arrested over the weekend in the Mojave Desert, where they had allegedly gathered to attempt to construct improvised explosive devices. According to Bill Essayli, the first assistant U.S. attorney for the Central District of California, they planned to set off the pipe bombs in a coordinated attack at midnight on New Year’s Eve targeting U.S. companies in Los Angeles and Orange County, Calif. 

“Last Friday, Dec. 12, the defendants took a significant step to carry out their plans,” Essayli said at a press conference Monday, noting that they traveled to a remote campsite near Twentynine Palms in San Bernardino County to begin assembling the bombs. “They had everything they needed to make an operational bomb.” 

Attorney General Pam Bondi described TILF as “a far-left, pro-Palestine, anti-government, and anti-capitalist group” in a social media post about the arrests. The four people arrested were identified as Audrey Ilene Carroll, Dante Garfield, Zachary Aaron Page and Tina Lai. They face charges of conspiracy and possession of a destructive device. FBI Director Kash Patel announced on Monday that a fifth individual with ties to the plot was arrested in New Orleans. 

Carroll had a poster at her home that said “Death to America. Long live Turtle Island and Palestine,” according to prosecutors. Turtle Island is a phrase used by some Native Americans to describe North America. 

TILF appears to be an organizer of an anti-Israel protest that targeted Wilshire Boulevard Temple, one of the largest synagogues in Los Angeles, earlier this month. 

The group posted a “call to action” on its Instagram urging followers to target the “bloody war criminals” and “genocidal monsters” from Elbit Systems, an Israeli defense company, because of the purported use of Elbit’s AI technology in Los Angeles’ Koreatown neighborhood. “Never let them live in peace,” the caption read. 

The post listed an address on Wilshire Boulevard for the demonstration but did not name the location. The address corresponds with the Wilshire Boulevard Temple building where an event to teach Koreans about security strategies, featuring an AI researcher from Elbit Systems, was taking place at the same date and time. 

Protesters entered the synagogue and disrupted the event, with one person shattering a glass vase and chanting profanities. Two people were arrested during the incident. L.A. Mayor Karen Bass called the activists’ actions “abhorrent” and pledged to send more security to houses of worship. 

Other posts on TILF’s Instagram call for violence.

“Peaceful protest will never be enough,” one graphic reads. “The only way out is through resistance.” 

The account’s most recent post was promoting a Palestine-themed holiday market in Los Angeles last weekend. 

Prosecutors announced on Monday that the investigation into the TILF New Year’s Eve plot was due in part to an executive order signed by President Donald Trump in September “to root out left-wing domestic terror organizations in our country such as antifa and other radical groups,” according to Essayli.
