The French state prosecutor says that police have discovered bomb-making material in a suburban parking lot linked to a dozen weekend arrests of terror suspects.

Francois Molins said on Wednesday that the material was found in a suburb east of Paris.

A dozen people were arrested last weekend suspected in the firebombing in September of a kosher grocery store north of Paris.

Molins said detention of the 12 suspects will be extended for 24 hours.
