A Jewish teacher in Marseille, a port city in southern France, was the victim of a stabbing attack by three people who claimed to support the Islamic State militant group (ISIS), a city prosecutor said Wednesday. The unidentified male teacher was stabbed in the leg and is expected to survive.

"The three people insulted, threatened and then stabbed their victim in the arm and leg. They were interrupted by the arrival of a car and fled," Marseilles prosecutor Brice Robin told Reuters.

The victim teaches history at a nearby Jewish school, according to French media.  The three men shouted anti-Semitic obscenities at him, before declaring their support for ISIS, city police prefect Laurent Nunez told the Local. They also showed the victim a photo of Mohammed Merah, a French jihadi who killed a rabbi and four children in 2012 at a Jewish school in Toulouse.

Authorities have not been able to locate the suspects. The attack occurred around 8 p.m. local time and came after last week's terrorist attacks that left at least 129 dead in Paris, which is about seven hours north of Marseille.

The militants from Friday's attacks are alleged to have been affiliated with ISIS. Paris authorities have asserted they acted in sets, first launching their attacks with three explosions near Stade de France stadium. The attacks also involved shootings at three different restaurants in central Paris and a hostage situation at the Bataclan concert hall in Paris involving more than 200 people.
