A van crashed into two bus stops in the French city of Marseille on Monday, killing one person and injuring at least one more, French media reported.

Authorities said the incident was not initially treated as a terrorism case, the Agence France-Presse news agency reported, citing a prosecutor’s statement. But fears of vehicle rammings remain high across Europe after last week’s twin attacks in Spain that claimed 15 lives.

The driver of the van in Marseille was arrested, France’s BFM-TV reported. The reason for the crash was not immediately clear.

BFM reported that a woman was killed at the second of the two bus stops attacked and that a man was injured at the first. Neither was identified.

On Monday, Marseille’s branch of France’s National Police announced on Twitter that an operation was ongoing and urged residents to avoid the famous Vieux-Port area, which is a draw for tourists.

Barcelona’s Las Ramblas boulevard, targeted in Thursday’s attack, is a similarly popular area and often packed with pedestrians.
