Four American tourists who were attacked with acid at a train station in Marseille have been identified as college students.
Boston College in Massachusetts said the female students were treated for burns at a Marseille hospital after they were sprayed in the face with acid on Sunday morning.
French authorities are not treating the incident as terror-related.
The four women were studying abroad, three of them at the college's Paris program.
The director of the college's Office of International Programs, Nick Gozik, said the women have been released from hospital and "it appears that the students are fine, considering the circumstances".
The students were identified as Courtney Siverling, Charlotte Kaufman, Michelle Krug and Kelsey Korsten.
A 41-year-old female suspect has been arrested in connection with the attack.
Boston College said police described the suspect as "disturbed".
