French police say they have discovered weapons and bomb-making equipment while hunting suspected Islamic terrorists.
The material was found overnight during searches of lockup garages near Paris after a dozen suspects were arrested across the country on Saturday.
Paris prosecutor Francois Molins said a shotgun, a revolver, bags of potassium nitrate, sulphur and a pressure cooker were among the items discovered at the premises. "These are all products useful in making improvised explosive devices," he added.
Authorities say the arrests made on Saturday show France is confronted with they call "an extremely dangerous terror network."
One of the operations resulted in police shooting dead an Islamist suspect linked to a grenade attack last month on a Jewish supermarket
Jeremie Sidney, 33, was killed during an exchange of gunfire at his home in the eastern city of Strasbourg.
