A city famed for its glamour and bustling streets seemed garbed in mourning as Parisians struggled with the shock of the multiple attacks that claimed scores of lives.
"All city facilities are closed today," Paris City Hall said on its website, listing schools, museums, libraries, sports halls, swimming pools, tennis courts, food markets and district town halls.
Only civil registration offices, to record marriages, will be open, it said, adding that security would be beefed up at district town halls. At noon, the city's main cinema chains said they too would close.
Outside a Cambodian restaurant where 12 people were killed, mourners placed flowers, a candle and the French tricolore.
On the national flag were written the defiant words "Fluctuat nec mergitur" -- the Latin slogan of Paris, meaning "It is buffeted by the waves, yet remains afloat."
The closures came after simultaneous assaults on a concert hall, restaurants and the Stade de France stadium.
It was the second terror strike in less than 10 months. In January, 17 people were killed, including five of the cartoonists at the satirical magazine Charlie Hebdo, in jihadist gun attacks.
"People are worried," Jean-Louis Masson, 50, who lives locally, told an AFP reporter.
"You can see that in the SMS messages that are going around. We were concerned for one of our children who was out last night, and we called to make sure she got home."
Masson's son, Adrien, 13, said he was a "bit worried. You get to be afraid that something could happen."
In a cafe, a man who gave his name as Luc, aged 46, said he was stupefied.
"They're unable to protect this city, that's what it's about."
The street outside the Galeries Lafayette department store was empty, after the emporium -- which initially declared it would remain open -- closed its doors.
At the approach of the Christmas season, the store's glitzy windows are usually crowded by young Parisians, eager to watch automated puppets in scenes from popular tales.
Today, the puppets went through their movements without an audience as fairy music played in the background. A line of Star Wars stormtroopers stood grimly to attention, impressing no one.
