BOSTON — A criminal complaint says two men are charged with conspiring to help the Islamic State group by plotting with a Boston terror suspect to kill U.S. citizens to support the group’s objectives.

Nicholas Rovinski, of Warwick, Rhode Island, was arrested Thursday. David Wright, of Everett, Massachusetts, was arrested last week.

Both men are charged with conspiring with Usaama Rahim, who was killed last week by terror investigators who had him under surveillance.
