Prosecutors in France say a bomb-making factory's been uncovered in the capital. The find happened as part of a police investigation into a suspected terror cell of radical Muslim extremists, whom detectives think are spread right across the country. Twelve people, who were detained in a weekend raid, will be held for another 24 hours, after chemicals used to make explosives were discovered in a lockup belonging to one of those arrested.

Paris prosecutor, Francois Molins, held a press conference to reveal the full extent of the finds, which he says represented a 'clear' threat. He said: "I can say that at this stage in our operations we have discovered in addition to a pump-action shotgun and handguns, bags containing potassium nitrate, sulphur, saltpetre, recipients like pressure cookers, car light bulbs. These are products and instruments that are useful for the manufacture of what are called improvised explosive devices."

Molins went on to say that everything will be done to put a stop to activities of what is obviously an extremely 'dangerous' terror cell. The raids, which led to the bomb-making haul were connected to an incident last month, where two men lobbed a grenade into a Jewish kosher supermarket in the suburb of Sarcelles, injuring one person.
