Police have shot and fatally wounded a man in an anti-terror operation in the French city of Strasbourg.
The operation was linked to an incident last month in which a small explosive device was thrown into a kosher grocery in Paris.
Three police officers were reportedly wounded after they confronted the man at his home on Saturday.
Operations were also under way elsewhere in France and the government said seven people were arrested.
Raids were carried out in Nice and Cannes in southeastern France as well as in an area of Paris, French media reported.
In a statement from the Elysee Palace, President Francois Hollande emphasised “the determination of the entire state to protect French people from all forms of terrorist threats”.
Among those arrested was the wife of the man fatally wounded in Strasbourg.
The incident at the grocery in the Paris suburb of Sarcelles on 19 September is said to have triggered a strong reaction among the local Jewish community.
One person was lightly injured in the attack.
