SEATTLE -

A man who pleaded guilty to plotting an attack on a Seattle military complex with machine guns and grenades is scheduled to be sentenced in federal court.

Abu Khalid Abdul-Latif has already agreed to a prison sentence between 17 and 19 years. The 35-year-old was to be sentenced in U.S. District Court Monday morning.

He pleaded guilty to conspiracy to murder U.S. officers and conspiracy to use weapons of mass destruction.

Abdul-Latif was arrested June 22, 2011. In conversations the FBI recorded with the help of the informant, authorities say Abdul-Latif and a co-defendant had discussed how they wanted to gun down people in the Military Entrance Processing Station in south Seattle as revenge for atrocities by U.S. soldiers in Afghanistan.
