Topeka ? Workers erected fences Thursday across the south Statehouse grounds as part of security measures for a weekend rally planned by a white supremacist group.

The National Socialist Movement, headquartered in Minneapolis, Minn., has scheduled a “white unity” rally for Saturday. The group’s Internet site features swastikas, and a manifesto posted there demands a nation in which only residents of “pure white blood” can be citizens.

One group planned a counterdemonstration on the Statehouse grounds, while the NAACP and civic leaders planned one in front of a nearby state office building, off the grounds.

Law enforcement agencies, led by the Kansas Highway Patrol, had the fences put up to separate the group’s leaders, members and supporters from counterdemonstrators. In addition, officers plan to limit access to the fenced-off demonstration areas and require people entering them to pass through metal detectors.

The patrol wouldn’t say how many law enforcement officers will be on duty for the event, but state and local agencies had 330 involved in security or in reserve for a 1994 Statehouse rally staged by the Ku Klux Klan.

State officials used similar security measures for the 1994 Klan rally, which saw only two minor incidents and no arrests made.

“We planned for, I guess, what could happen,” said Lt. John Eichkorn, the patrol’s spokesman. “We definitely wanted to be prepared.”

The state plans to close the Capitol until 3 p.m. Saturday, the time the white supremacist rally is supposed to end.

In addition, only 30 National Socialist Movement members will be allowed on the south Statehouse steps, where speeches are planned.

Fences and about 30 yards of open space are supposed to separate the group from supporters on the southwest side of the Statehouse grounds and counterdemonstrators on the southeast side.

Streets around the Statehouse are to be closed. Law enforcement agencies are prohibiting weapons, chemical irritants, packages, backpacks, coolers, cans, bottles and even signs and flags mounted on poles.

National Socialist Movement officials weren’t available by phone at the group’s headquarters, and a message left by The AP wasn’t returned. On its Internet site, the group said it hoped to at least double participation from a rally a year ago at the Minnesota state capitol in St. Paul.

About 35 white supremacists, including Klan members, participated in the Minnesota rally and were largely drowned out by boos and shouts from some 1,500 counterdemonstrators. There were four arrests.
