But he urges vigilance, adding: "It's a form of war in this country, because we can see that the threat of terrorism is everywhere, it's very difficult to detect.
"There's been a strong mobilisation of all our intelligence services, the police and the courts but no system can prevent an attack 100 percent. So a heightened vigilance is needed, the vigilance of all our citizens."

12:31 GMT - Attack on democracy - Nathalie, a Swiss woman passing through Paris, says: "I think it's nice that these people are coming. People are deserting faith, churches are empty... it takes something like this to bring them back.

"We want to inform French people of our mobilisation and also welcome the rallies held by our fellow citizens yesterday and again today, and certainly again at the weekend, and this willingness to fight for our democracy, for our tolerance," he says.
"I also call on everybody to be responsible. Today, last night, this morning there is information circulating on the web but also in your broadcasts that could, let me repeat this, undermine the work of the security forces."
11:50 GMT - Sarkozy at Elysee - Former French president Nicolas Sarkozy has been at the Elysee presidential palace for talks with President Francois Hollande on the response to the attacks.

11:25 GMT - Hebdo 'suffering' - Charlie Hebdo columnist Patrick Pelloux says the remaining staff will soon meet, as he announced the next edition would go ahead.

Twelve people, including five cartoonists, were killed in Wednesday's attack.
11:19 GMT - Silent tribute - People across France observed a minute of silence earlier, broken only by church bells. Crowds of people stood silently in public squares, schools and outside official buildings. Bells tolled at Paris's Notre Dame cathedral and in churches across the country.
