DES MOINES, Iowa (AP) — The state is seeking to overturn a 1974 federal court ruling that gave formal religious status to a prison group that officials say is nothing more than a front for a white-supremacist group.

Iowa attorneys have filed court papers seeking to revisit whether the Church of the New Song deserves constitutional protection as a religion.

State lawyers, citing evidence that has not yet been made public, contend that the prison religion is a security threat and that "regular meetings of CONS have been used to plan bad acts, including assaults."

Patrick Ingram, an Iowa City attorney appointed to represent the prisoners, said state authorities "can't point to anything and say, 'This is that part that's white supremacist.' "

The Church of the New Song was founded in the 1970s by Harry Theriault, a federal prisoner in Atlanta. It once considered porterhouse steaks one of its communion elements.

CONS inmates insist that they have been singled out for their beliefs and put into high-security lock-down in the state prison at Fort Madison. PARIS (AP) — Vandals scrawled swastikas and other Nazi references on the walls of the Grand Mosque of Paris, the most prominent Muslim religious site in France, religious leaders said Monday. Authorities also investigated a possible arson attack on a memorial for Jews deported to Auschwitz in World War II, amid an increase in anti-Muslim and anti-Jewish vandalism.

The mosque vandals scrawled about a dozen swastikas, other Nazi references and "Get Out" on the white walls around the imposing, decades-old house of worship in southeastern Paris.

"This intolerable act of Islamophobia is a worrying symptom in the capital," said Dalil Boubakeur, director of the Paris mosque.

Separately, police in a northeastern Paris suburb investigated the suspected arson attack at the Jewish site. Firefighters extinguished a blaze Sunday that charred a wooden rail car at the memorial in Drancy, the site of a transit camp used to deport thousands of Jews to Auschwitz.

A handwritten note found at the site referred to the little-known "Islamic group for Palestine" and carried the name "Bin Laden" on it next to a swastika.

"We have witnessed several demonstrations today that are anti-Semitic and racist," French Interior Minister Dominique de Villepin told reporters during a visit to eastern France. He said the attacks were "completely unspeakable, completely ignominious."

France, home to western Europe's largest populations of both Jews and Muslims, has faced an upsurge in anti-Semitic and anti-Muslim violence in recent years.

The interior minister said earlier this month that neo-Nazi groups now count about 3,000 members, and were responsible for 65 violent acts last year — up from 27 in 2003.

In response, officials have stepped up security around Jewish and Muslim sites in France.
