The first person indicted under a federal anti-terrorism law adopted after the Sept. 11 attacks was sentenced Monday to 25 years in prison for attempting to smuggle anti-aircraft missiles into the United States from his native China.

Yi Qing Chen was convicted in October of attempting to ship the shoulder-fired QW2 missiles as well as launch and operational hardware to a man who turned out to be an undercover FBI agent. He was arrested in 2005 before the missiles could be delivered.
