French police shot dead a man during an early morning anti-terrorism raid in the eastern city of Strasbourg on Saturday.
Three officers were injured in the shooting after apparently being confronted by the man as they forced their way into his home.
Police sources say the suspect shot at officers first.
A second resident, a woman, was detained.
Numerous raids took place all over France on Saturday including Paris and the southeastern city of Cannes.
A statement from the office of French President Francois Hollande confirmed that seven people were arrested in total.
The raids are believed to be linked to last month’s bombing of a Jewish grocery store in Paris.
On September 19, one person was slightly injured when what’s described as a low-grade explosive device went off in the Sarcelles suburb.
The blast has caused considerable alarm among the city’s Jewish community.
