One of four men accused of plotting attacks on Southern California military sites and Jewish targets pleaded guilty to terrorism conspiracy charges, the Associated Press is reporting.

Levar Haley Washington, 28, admitted committing seditious conspiracy and using a firearm to further that conspiracy. He faces up to 25 years in prison when he is sentenced in April.
Another man, Kevin James, was also expected to plea guilty to a terrorism charge. He faces up to 20 years in prison.

The plot was hatched in prison and James, Washington and two others were part of a cell of radical Muslims planning attacks on military facilities, Shuls and other sites in the Los Angeles area on Yom Kippur, September 11, and other significant dates.

Police uncovered the plot by chance, while investigating gas station robberies that authorities say were committed to finance the attacks.

Also indicted in the case were Gregory Vernon Patterson and Hammad Riaz Samana. Samana is a Pakistani national, while the others are U.S.-born Muslim converts.
