The Vatican has issued a statement calling the violence in Paris "an attack on all humanity".
"We condemn (it) in the most radical way together with The Pope and all those who love peace," said Vatican spokesman Father Federico Lombardi in a statement.
The statement calls for "a decisive, supportive response on the part of all of us as we counter the spread of homicidal hatred in all of its forms".
France has tightened its border controls in the wake of the attacks in Paris, but most air and rail services appear to be running normally.

It's seven years since a major terror attack in Mumbai used similar tactics to those seen in central Paris on Friday.
Europe Correspondent Damian Grammaticas has this on the implications for France and for European security.
Quote MessageWhat happened in Paris last night is exactly what Europe's security services have long feared, and tried to foil. Simultaneous, rolling attacks, with automatic weapons and suicide bombers in the heart of a major European city, targeting multiple, crowded public locations. These tactics have been used before in Mumbai and elsewhere. But how they've come to Europe many questions will have to be answered. Were the attackers French citizens, if so, how they were radicalised, armed and organised? In France, in Syria, by whom? Why weren't they detected? Is France, after two major attacks this year, uniquely vulnerable? Or does the carnage in Paris mean all of Europe faces new threats to our public places and events? And if a Syrian link is proven, will France recoil from that conflict or will it redouble its commitment to the fight against radical groups there?

The Guardian has spoken to Mark Colclough, a 43-year-old British-Danish psychotherapist, who was with a colleague on Rue de la Fontaine when he saw a gunman attack a cafe, external:
Quote MessageHe was left handed and shooting in bursts of three or four shots. It was fully intentional, professional bursts of three or four shots. He killed three or four individuals who were sitting in the chairs in front of the cafe. We saw them get shot down. They fell off their chairs onto the ground. He then swivelled and shot through a car drivers’ window. We then saw him walk into the cafe. He swivelled right and then swivelled left and opened fire. That is when we dived for cover. We heard a total of maybe 15 or 20 shots, then everything went quiet.
