An Islamist suspected of a grenade attack on a Jewish market was shot and killed by police in the northeastern city of Strasbourg on Saturday and 11 others detained in what prosecutors called a “vast anti-terrorist operation”.

Elite police squads carried out simultaneous operations against a network of radical Islamists in the Paris region and in Strasbourg, Nice and Cannes early on Saturday.

The raids were connected to a September 19 incident in the Paris suburb of Sarcelles in which two men, including the suspect killed on Saturday, threw a grenade into a Jewish kosher supermarket, wounding one person and causing minor damage, said Paris prosecutor Francois Molins.

“A vast anti-terrorist operation was conducted this morning,” Molins told a news conference.

He named the deceased as French citizen Jeremie Sidney, 33, who he said had spent two years in prison for drug-dealing and belonged to a radical Islamist movement.

“Jeremie Sidney appeared to be a delinquent converted to radical Islam who belonged to a group suspected, without certainty, to want to enter into jihad,” Molins said.

France’s Jewish community has been on edge after a series of attacks in recent months. In the worst incident, three Jewish children and a rabbi were among seven people shot dead in March by an al-Qaeda-inspired gunman.
