Two women suffered facial injuries and two other travellers, all in their twenties, were left nursing burns following the attack.
It is understood the tourists were in Gare Saint-Charles station in Marseille just after 11am this morning when the 41-year-old female attacker sprayed them with hydrochloric acid.
Hydrochloric acid, if strongly concentrated, can cause severe burns. It can also be dangerous if it comes into contact with a person’s eyes.
All four of those involved in the incident were thought to be American women, who were travelling as a party between Paris and Marseille.
The acid was thought to be in a spray canister sold in DIY shops for cleaning purposes.
