We are going to pause our live coverage for now, but you can continue to follow developments on the BBC News homepage and on Twitter, external.

Here are today's key developments:

Francois Hollande speech

• The French president said he would table a bill in the coming week to extend France's state of emergency to three months.
• He called for changes to the French constitution to allow French nationals to be stripped of their citizenship if they were convicted of terror offences.
• He pledged significant additional resources and personnel to French security forces.
• He vowed to intensify air strikes against Islamic State in Syria.

The investigation

• French prosecutors identified Moroccan-origin Belgian Abdelhamid Abaaoud as the mastermind behind the Paris attacks. Abaaoud is thought to be in Syria.
• Prosecutors also identified one of the attackers as Ahmad Almohammad. Almohammad, a Syrian passport-holder, reportedly entered the EU via Greece along with refugees.
• Two of the seven people arrested in Belgium on Saturday were charged with terror offences. Five have been released, including a brother of two of the suspected assailants.
• Mohamed Abdeslam, whose brother Brahim blew himself up and whose other brother Salah is wanted by police, said he had no idea where Salah was and no advance warning of the attacks.
• French police are still hunting for Salah Abdeslam, thought to be one of the gunmen. Reports he had been detained during a raid in the Belgian town of Molenbeek turned out to be false.  
• Italian police were alerted to look out for a black Seat car thought to be connected to the attacks that may have crossed into Italy. 

The fight against Islamic State

• Francois Hollande called the attacks an "act of war"and vowed to "destroy" IS.
• IS issued two new propaganda videos from Iraq, celebrating the attacks in Paris and threatening Washington DC.  
• US President Barack Obama ruled out sending in US ground troops to fight IS in Iraq and Syria. Mr Obama called the attacks "a sickening setback" but said the US would "intensify" air strikes.

• The Pentagon said it would step up intelligence sharing with France in the wake of the attacks.

US Republican presidential candidate and businessman Donald Trump has said he would consider closing mosques in the US. 

"I would hate to do it, but it's something that you're going to have to strongly consider," Mr Trump told MSNBC.

He said the US would have to "watch" and "study" mosques because "lots of talk is going on" in them, and warned that US citizens would have to prepare to give up certain civil liberties.

Over the weekend, Mr Trump suggested that the situation in Paris would have been different if some of the victims had been armed.

French nationals returning from Syria could be put under house arrest and subject to tough surveillance, AFP reports, citing a government source.

Addressing the French parliament earlier today, President Francois Hollande outlined a series of measures designed to combat extremism, including extending France's current state of emergency and giving authorities more powers to deport foreign nationals deemed to pose a threat.

A police operation taking place in the Neudorf area of Strasbourg this evening is over, according to local media, and Salah Abdeslam "was not found there".

French media had reported a "large" operation after a witness thought they saw the suspect in Friday's attacks.

A police spokesman confirmed to the BBC that there was an ongoing operation in the eastern French city, but would not give any details.

IS has a "24-hour help desk" available for messaging, recruiting and planning, according to a report by NBC News, external.

The desk is for "helping would-be jihadists use encryption and other secure communications in order to evade detection by law enforcement and intelligence authorities," counter-terrorism analysts affiliated to the US Army told the broadcaster.

Left-leaning French newspaper Liberation's Tuesday front page focuses on Francois Hollande's announcement that the state of emergency will be extended for three months:

US Secretary of State John Kerry has arrived in France to meet with French officials and embassy staff. 

Mr Kerry spoke shortly after arriving to pay tribute to the city.

"As history knows, Paris has seen even darker days and overcome them," he said "No one should doubt that the light still shines in the City of Light."

"We are all Parisians."

 He said the US embassy in Paris would be lit up tonight in the red, white, and blue of the French flag.

At least 13 Republican state governors in the US say they intend to suspend programmes to resettle Syrian refugees in the wake of the attacks in Paris. 

Reports that one of assailants in Paris entered Europe through Greece posing as a refugee have strengthened calls from some quarters for tougher restrictions.

The state of Alabama has so far not taken in any Syrian refugees, external, but the southern state's governor Robert Bentley has said that he "will not place Alabamians at even the slightest possible risk of an attack on our people".

In Michigan, where it has been reported that 200 Syrians have been resettled in the past year, Governor Rick Snyder said he will suspend the acceptance of new refugees pending "a full review of security clearances and procedures".

Alabama, Texas and several other states issued similar statements but a State Department spokesman said the legality of the move was unclear.   

"Whether they can legally do that, I don't have an answer for you," Mark Toner said. "I think our lawyers are looking at that."   

States saying no:

• Texas
• Michigan
• Louisiana
• Indiana
• Arkansas
• Alabama
• Massachusetts

• Ohio 
• Arizona
• Mississippi
• Iowa
• Illinois
• North Carolina
• Wisconsin
• New Hampshire

Speaking at the G20 meeting on Monday, President Obama said the US would continue to accept refugees, including Syrians, following "rigorous" security screenings.

"Slamming the door in their faces would be a betrayal of our values," he said.

A Twitter account has been set up to commemorate victims of the attacks in Paris.

Anyone wanting to send an image or tribute can use the hashtag #enmémoire.

Omar Ismail Mostefai, a 29-year-old Frenchman of Algerian origin, was among the three gunmen who killed 89 people at the Bataclan concert hall - the worst single attack of the night.

Mostefai was known to French security services and was identified by the print on a severed finger found at the scene.

The BBC's James Longman visited Courcouronnes, the Paris suburb where Mostefai grew up, and spoke to a former gangster who says he knew him.

The captain of France's football team has said the players had doubts about playing England in a friendly in London on Tuesday, but were told they had to by the president of the French Football Federation. 

"The president made the best decision, I think, to play this game," Hugo Lloris told a news conference at Wembley Stadium. "The French nation is more important than French football team." 

France were playing Germany at the Stade de France on Friday when suicide bombers targeted the stadium. Midfielder Lassana Diarra lost a cousin in one of the shooting attacks elsewhere in Paris, while forward Antoine Griezmann's sister escaped unhurt from the Bataclan theatre. 

"The last three days were a bit dramatic. We were in mourning all together," Lloris said. "We will try to escape from it for 90 minutes. There will be a lot of emotion from the players, but it will be a great moment of solidarity."
