Two men already facing federal indictments for conspiracy to support ISIS are facing additional charges.
David Wright, 26, of Everett, and Nicholas Rovinski, 25, of Warwick, Rhode Island, are now also charged with conspiracy "to commit acts of terrorism transcending national boundaries," the U.S. Attorney's Office said in a statement Thursday.
Both men pleaded not guilty last year to charges of conspiring to provide material support to a terrorist organization. Prosecutors allege they conspired with Usaamah Rahim, 26, on a plan to behead blogger Pamela Geller. The plan was not carried out.
Rahim was shot and killed by law enforcement officials who say he attacked them in a Roslindale parking lot on June 2, 2015.
In the superseding indictment, prosecutors say Rahim had been in contact with ISIS members overseas. In May 2015, Rahim allegedly communicated instructions he received regarding the murder of an individual to Wright, according to the statement.
Since their arrest, prosecutors say Rovinski has written letters to Wright from prison discussing "ways to take down the U.S. government."
