An alleged terror plot involving several locations in the Los Angeles area has been thwarted, US federal authorities said.
A man was arrested by federal agents on Friday in connection with the suspected strike in Southern California.
Army veteran Mark Domingo, 26, who served in Afghanistan, allegedly planned to bomb a white supremacist rally on Sunday as retribution for the New Zealand mosque attacks.
Domingo was arrested on a charge of providing material support to terrorists and a criminal complaint said he had been planning since March to "manufacture and use a weapon of mass destruction in order to commit mass murder".
Court papers show that Domingo discussed with an informant different types of attacks that included targeting Jewish people, churches and police officers.
Domingo allegedly said he wanted revenge for attacks on mosques in New Zealand that killed 50 people last month.
Domingo allegedly bought parts, including nails, for an improvised explosive device that would be remotely triggered, but in fact contained inert materials, FBI agent Tasha Coolidge said in an affidavit filed in US District Court in Los Angeles.
If they survived the planned bombing at Bluff Park, Domingo discussed launching further attacks on the ports of Long Beach and Los Angeles or on a train.
White nationalists never showed up to the planned event in Bluff Park, but a large group of counter protesters demonstrated.
