BIRMINGHAM, Ala. -- Victims of an anti-abortion extremist who pulled off several bombings across the South said that he is taunting them from the nation's most secure federal prison.

But authorities said there's nothing they can do to stop Eric Rudolph.

He was captured after a five-year manhunt and pleaded guilty in deadly bombings at the 1996 Olympics in Atlanta, and an Alabama abortion clinic.

He's serving life behind bars at the Supermax penitentiary near Florence, Colo.

A supporter who maintains an Army of God Web site has been posting Rudolph's long essays on the Internet. The loose-knit group is the same one Rudolph claimed to represent in letters sent after the blasts.

In one essay, Rudolph seeks to justify violence against abortion clinics. In another essay, he mocks a former abortion clinic nurse.

She was nearly killed in the 1998 bombing in Birmingham. Rudolph uses pseudonyms rather than naming the woman or her husband.

The Bureau of Prisons failed to respond to repeated inquiries from The Associated Press about whether Rudolph's writings violate prison rules.

But U.S. Attorney Alice Martin said there's nothing the prison can do to restrict Rudolph, or the Virginia supporter who keeps posting his writings.

Supermax holds some of the nation's most infamous inmates, including Unabomber Theodore Kaczyinski; Oklahoma City bombing co-conspirator Terry Nichols; September 11 conspirator Zacarias Moussaoui; and would-be shoe-bomber Richard Reid.
