WASHINGTON — Hate crime incidents in the United States rose last year by nearly 8 percent, the FBI reported today, as racial prejudice continued to account for more than half the reported instances.

Police across the nation reported 7,722 criminal incidents in 2006 targeting victims or property as a result of bias against a particular race, religion, sexual orientation, ethnic or national origin or physical or mental disability. That was up 7.8 percent from the 7,163 incidents reported in 2005.

Although the noose incidents and beatings among students at Jena, La., high school occurred in the last half of 2006, they were not included in the report. Only 12,600 of the nation's more than 17,000 local, county, state and federal police agencies participated in the hate crime reporting program in 2006 and neither Jena nor LaSalle Parish, in which the town is located, were among the agencies reporting.

The Jena case began in August 2006 after a black student sat under a tree known as a gathering spot for white students. Three white students later hung nooses from the tree. They were suspended by the school but not prosecuted.

Six black teenagers, however, were charged by LaSalle Parish prosecutor Reed Walters with attempted second-degree murder of a white student who was beaten unconscious in December 2006.

The charges have since been reduced to aggravated second-degree assault, but civil rights protesters have complained that no charges were filed against the white students who hung the nooses.

The FBI report does not break out the number of noose incidents but the two most frequent hate crimes in 2006 were property damage or vandalism, at 2,911 offenses, and intimidation, at 2,046 offenses. There were 860 aggravated assaults and 1,447 simple assaults. There were three murders, 6 rapes and 41 arsons. Other offenses included robbery, burglary, larceny, and motor vehicle theft.
