A man who helped plot an attack with machine guns and grenades on a Seattle military complex has been sentenced to 17 years in prison.

Walli Mujahidh was sentenced Monday after pleading guilty in December to conspiracy to kill officers of the U.S., conspiracy to use weapons of mass destruction, and unlawful possession of a firearm.

The 33-year-old Mujahidh of Los Angeles was one of two men arrested in June 2011 when they arrived at a warehouse to pick up weapons. An informant had alerted authorities to the plan to attack the Military Entrance Processing Station.

A Seattle co-defendant in the case, 35-year-old Abu Khalid Abdul-Latif, was sentenced last month to 18 years in prison. He pleaded guilty to conspiracy to use weapons of mass destruction and murder U.S. officers.
