A federal grand jury in Boston has indicted two men on charges they conspired to help the Islamic State group by plotting with a Boston terror suspect to kill U.S. citizens to support the group's objectives.

Federal authorities Thursday announced the indictments of Nicholas Rovinski of Warwick, Rhode Island, and David Wright of Everett, Massachusetts.

They were charged last week with conspiring to provide material support to terrorists by plotting with Boston terror suspect Usaamah Rahim to behead blogger Pamela Geller, who wasn't harmed. Rahim was killed June 2 by investigators who say Rahim lunged at them with a military-style knife.

Rovinski and Wright are expected in court Friday for a detention hearing. Prosecutors are expected to ask that the two men be held without bail while awaiting trial.
