NEW YORK — Federal prosecutors in Manhattan charged a senior official in Iran’s Revolutionary Guard and three other men connected to the country’s government with participating in a failed plot to assassinate a human-rights activist in Brooklyn in 2022, according to a new indictment made public Tuesday.

The plot to kill the activist, Masih Alinejad, who has criticized Iran’s repression of women, was disrupted by the U.S. government and had already led to federal murder-for-hire charges against members of an Eastern European criminal organization with ties to Iran.

The new charges are the first to directly accuse a high-ranking official in the Revolutionary Guard with a role in the plot. The group is Iran’s primary military force, executing its foreign policy across the Middle East and controlling much of the country’s economy. The official, Ruhollah Bazghandi, is described in the indictment as a brigadier general with the Revolutionary Guard.
