WASHINGTON (Reuters) -U.S. prosecutors unveiled criminal charges on Monday against two alleged leaders of a white supremacist gang, accusing them of soliciting attacks on Black, Jewish, LGBTQ people and immigrants in hopes of inciting a race war.

The group, dubbed “The TerrorGram Collective” used the social media site Telegram to celebrate white supremacist attacks around the world and solicit racially motivated violence, according to an indictment unsealed in federal court in Sacramento, California.

The group’s targets also included U.S. government officials and critical infrastructure sites, with an overall goal of causing societal collapse in the United States, U.S. Justice Department officials told an online news conference.
