(CNN) Five suspects who lived on a New Mexico compound were charged on Wednesday with conspiring to provide material support in preparation for attacks on federal law enforcement officers and members of the military.

A federal grand jury in Albuquerque, New Mexico, returned a superseding indictment charging the suspects with federal offenses related to terrorism, kidnapping and firearms violations. The superseding indictment replaces one returned by a grand jury last year and includes more serious charges.

"The superseding indictment alleges a conspiracy to stage deadly attacks on American soil," US Attorney John C. Anderson said Thursday in a news release from the US Department of Justice.

The defendants are Jany Leveille, 36, Siraj Ibn Wahhaj, 40, Hujrah Wahhaj, 38, Subhanah Wahhaj, 36, and Lucas Morton, 41, according to the Justice Department. Amy Sirignano, the attorney for the defendants, declined to comment when reached by CNN.

"No comment at this time, until we learn more about the new charges. All of our clients will be pleading not guilty at the arraignment next week," she said in an email.
