The victims of the acid attack studying at Boston College have been treated for burns and have been discharged from the hospital. Two people were injured on the face, one was injured in the eye, a spokesperson for the Marseille prosecutor's office told AP.
The acid attack on an American student in France occurred at around 11am on September 17 at the Marseille-Saint Charles station. Fourteen firefighters and four rescue vehicles were present at the scene as soon as the incident occurred.
According to Boston College, the four female students are studying at the school's international programs. Three students Courtney Siverling, Charlotte Kaufman and Michelle Krug are studying in Paris. The other, Kesley Kosten, is a student at Copenhagen Business School in Denmark.
We have been in contact with students and their parents and have kept in touch with French authorities and the US Embassy about the incident, said Nickzik Go, director of the Boston Schools international program office.
French investigators do not consider this a terrorist attack but have not ruled out the possibility. According to a spokesperson for the Marseille prosecutor's office, the suspect in the acid crossing did not make any extreme threats.
According to La Provence newspaper in Marseille, the mental attacker was unstable. The suspect's identity was not disclosed.
US Embassy spokesman in Paris Alex Daniels said the Embassy did not comment on the incident and said the US consulate in Marseille was working with the investigation agency.
The port city of Marseille, about 800km southeast of Paris, has seen at least two other attacks in recent months.
In August, a man drove a truck into two bus stations in the Vieux- port area, killing one person and injuring another. In January, a 15-year-old Kurd attacked a jewish teacher.
Outside France, in the UK, authorities said acid attacks have tripled in the past three years, raising concerns that anyone could be a victim.
