The Holy Land Foundation

The Texas-based Muslim charity and five of its organizers were convicted in November of funneling more than $12 million to the militant Palestinian group Hamas. A federal jury in Dallas delivered the verdicts a year after another trial ended in a hung jury.

The Liberty City Seven

A Miami group of alleged homegrown terrorists was tried twice on charges that it plotted to blow up the Sears Building in Chicago and several FBI offices. Each trial ended with a hung jury. One defendant was acquitted during the first trial, but he has been deported to his native Haiti. A new trial against the other defendants is set to begin next month.

Shahawar Matin Siraj

The Pakistani immigrant and high school dropout was convicted in May 2006 by a federal jury in Brooklyn, N.Y., of plotting to plant explosives at the 34th Street subway station in Manhattan. In January 2007 he was sentenced to 30 years in prison.

Chao Tung Wu

He pleaded guilty in April 2006 to a series of federal smuggling charges, admitting among other things that he conspired to bring Chinese-made shoulder-fired missiles into the United States. The government alleged the missiles were to be used to shoot down aircraft. The Los Angeles-based FBI investigation, in which 87 individuals were charged in a conspiracy that included plans to smuggle counterfeit currency, drugs and other contraband into the country, was dubbed Operation Smoking Dragon.

Richard Reid

The so-called "shoe bomber" was sentenced to life in prison in December 2003. Reid, a British national, boarded an American Airlines flight from Paris to Miami in December 2001 with plans to detonate a bomb hidden in his shoe. Passengers and flight personnel subdued him, and he was charged with attempting to use a weapon of mass destruction against U.S. nationals.

Zacarias Moussaoui

Often referred to as "the 20th hijacker," he was sentenced in May 2006 to life without parole after pleading guilty to a conspiracy charge and admitting he was to be part of the Sept. 11 attacks. Moussaoui, a French citizen of Moroccan descent, was jailed on immigration charges three weeks before the planes were hijacked.

The Lackawanna Six

Members of what the government charged was a "sleeper cell" of Yemeni Americans living in Upstate New York were arrested after attending an al-Qaeda training camp in Afghanistan in 2001. All pleaded guilty to a terrorism-related charge and agreed to provide information to the FBI. They were sentenced to terms of eight to 10 years.

Sheikh Omar Abdel-Rahman

He and nine coconspirators were convicted in federal court in Manhattan of plotting to bomb the United Nations building, FBI offices, and other New York landmarks. The government also alleged they were behind the 1993 World Trade Center bombing in which six people were killed. Convicted after a nine-month trial that ended in October 1995, the blind Egyptian cleric was sentenced to life in prison without parole. His co-defendants were sentenced to terms ranging from 25 years to life.
