Paris has extended a ban on public gatherings introduced after the terror attacks in the French capital until 30 November, the start of UN climate talks, the city's police headquarters said today.
In a statement the prefecture recalled the "extreme seriousness" of last week's attacks, which left 130 people dead and prompted the government to put in place a three-month state of emergency.
Authorities have already banned two citizens' rallies planned around the climate summit that will be attended by 138 heads of state and government after the worst-ever terror attack on French soil.
The French government has said it will not "give in" to terrorism and insists the long-anticipated conference will go ahead.
A state of emergency put in place immediately after the 13 November attacks was this week extended to three months.
It allows government to place under house arrest anyone considered to be a threat to security, and police to launch raids without advance authorisation from the courts.
Hundreds of such raids have taken place this week, turning up weapons arsenals in people's homes - a rocket-launcher in one case - and the flag of the so-called Islamic State group which claimed the attack.
While the state of emergency does not allow control of the press, the interior ministry reserves the right to block websites or social media accounts promoting terrorism.
It also allows authorities to dissolve groups or associations participating in, facilitating or inciting acts which threaten public safety.
Meanwhile, the Paris prosecutor Francois Molins said a second suicide bomber at the Stade de France, who also came via Greece in October, has been identified. No further details were given.
UN unanimously approves 'all necessary measures' to fight IS
The UN Security Council has authorised countries to "take all necessary measures" to fight the so-called Islamic State group in a resolution that won unanimous backing a week after the Paris attacks.
The French-drafted measure calls on all UN member states to "redouble and coordinate their efforts to prevent and suppress terrorist attacks" committed by IS and other extremist groups linked to Al-Qaeda.
British Prime Minister, David Cameron, says the vote to back action against the so-called Islamic State shows the world is united against the "evil death cult."
Mr Cameron called the vote on the French-drafted text an "important moment".
"The world has united against ISIL (Islamic State). The international community has come together and has resolved to defeat this evil, which threatens people of every country and every religion," he said in a statement.
"The UN Security Council has unanimously backed action against this evil death cult in both Syria and Iraq.... Today's vote shows beyond doubt the breadth of international support for doing more in Syria and for decisive action to eradicate ISIL."
Britain is taking part in airstrikes on Islamic State targets in Iraq and the government intends to seek parliamentary approval to extend these to Syria - if it can secure a consensus across parties.
Meanwhile, the United States and its allies targeted IS with 20 air strikes in Iraq and 22 in Syria yesterday, the US military said.
Six of the strikes in Iraq hit three IS tactical units, a command and control facility and fighting positions near Ramadi, the military said.
The attacks in Syria included 13 strikes near Mar'a, hitting IS tactical units, headquarters, and three IS buildings, it added.
One attack near Abu Kamal, Syria, struck an IS oil collection point, the statement issued today said.
