PARIS -- Four American college students were attacked with acid Sunday at a train station in the French city of Marseille, but French authorities so far do not think extremist views motivated the 41-year-old woman who was arrested as the alleged assailant, the local prosecutor's office and the students' school said. 

Boston College, a private Jesuit university in Massachusetts, said in a statement Sunday that the four female students were treated for burns at a Marseille hospital after they were sprayed in the face with acid on Sunday morning. The statement said the four all were juniors studying abroad, three of them at the college's Paris program.

"It appears that the students are fine, considering the circumstances, though they may require additional treatment for burns," Nick Gozik, who directs Boston College's Office of International Programs. "We have been in contact with the students and their parents and remain in touch with French officials and the U.S. Embassy regarding the incident."

Police in France described the suspect as "disturbed" and said the attack was not thought at this point to be terror-related, according the university's statement.

The Paris prosecutor's office said earlier Sunday that its counter-terrorism division had decided for the time being not to assume jurisdiction for investigating the attack. The prosecutor's office in the capital, which has responsibility for all terror-related cases in France, did not explain the reasoning behind the decision.

A spokeswoman for the Marseille prosecutor's office told The Associated Press in a telephone call that the suspect did not make any extremist threats or declarations during the late morning attack at the city's Saint Charles train station. She said there were no obvious indications that the woman's actions were terror-related.
