Fort Dix Six

Six foreign-born Muslims were accused Tuesday of planning to assault the Army base and slaughter scores of U.S. soldiers with automatic weapons and rocket-propelled grenades. The unidentified clerk is being credited with tipping off authorities in January 2006 after one of the suspects asked him to transfer a video to DVD that showed 10 men shooting weapons at a firing range and calling for jihad, prosecutors said. "If we didn't get that tip," said U.S. Attorney Christopher Christie, "I couldn't be sure what would happen." FBI agent J.P. Weis called the clerk the "unsung hero" of the case. Authorities said there was no direct evidence connecting the men to any international terror organizations such as Al Qaeda. But several of them said they were ready to kill and die "in the name of Allah," prosecutors said in court papers. Weis said the U.S. is seeing a "brand-new form of terrorism," involving smaller, more loosely defined groups that may not be connected to Al Qaeda but are inspired by its ideology. "These homegrown terrorists can prove to be as dangerous as any known group, if not more so. They operate under the radar," Weis said.
