French authorities say they opened a counterterror investigation after two women died in a knife attack at the main train station in the southern city of Marseille.
The assailant was shot dead by soldiers patrolling the area near Saint-Charles station, police said on October 1.
Police sources and witnesses were quoted as saying the attacker shouted “Allahu akbar” (God is greatest) as he carried out the attack.
The prosecutor's office in Paris said that a counterterrorism probe was opened.
Interior Minister Gerard Collomb said on Twitter that he was heading to Marseilles.
France has been under a state of emergency since November 2015 attacks in Paris that left 130 people dead.
The government has deployed about 7,000 troops across the country to guard high-risk areas such as transport hubs, tourist sites, and religious buildings.
