We're bringing to an end our live coverage of the dramatic near simultaneous police raids that resulted in the killings of the two Charlie Hebdo suspects and a third gunman who took several people hostage at a supermarket in eastern Paris.
France is continuing to mourn for the Charlie Hebdo victims, as well as four of the hostages killed during Friday's supermarket siege. You can follow further updates, as well as background material on the story, on the BBC News website.

Paris is a big but small city so wherever you live it is close to what is happening. This is also why Paris will always rebound stronger and more unified as the community spirit is what really makes it the city of lights. Vive la France :-)
Police video of raid
Another video released by French police shows the moment special forces launched a raid on the print workshop in Dammartin-en-Goele, where the Charlie Hebdo suspects were hiding out.

Dramatic footage
Amateur footage broadcast by France2 TV shows the storming of the supermarket. The shop shutters open slowly to reveal a body lying as police quickly approach the entrance. They fire into the building.
The shot is frozen when a man dressed in black - possibly the hostage taker - appears running towards the door. Dozens of police enter the supermarket and hostages run onto the street. A body is then seen being dragged out of the shop. It is not clear whether it is that of the gunman.

It is likely four of the hostages were killed when the gunman entered the Jewish supermarket, and not during the special police operation that ended the siege. The gunman had called a TV station to say that he had killed four of the hostages.

Coulibaly and his girlfriend, Hayat Boumeddiene, spoke more than 500 times to the Kouachi brothers over the phone.
Printing works employee 'hid'

Kouachi brothers' neighbours 'found weapons'
The Globe and Mail's Mark Mackinnon tells BBC Newshour that he met a Tunisian woman who was living next door to one of the Kouachi brothers.
"She had been concerned about her neighbours for quite some time, and described how she heard the brothers praying loudly through the walls. She thought they may be extremists so her husband broke in with the help of a plumber and discovered a cache of weapons. The brothers caught them, and forced them to promise not to tell the police."

Police 'heard gunman praying'
According to French media, police were able to monitor what was happening inside the supermarket when the gunman, Amedy Coulibaly, failed to hang up properly after speaking to them. The BFMTV news channel says this was what enabled the police to hear what was going on in the background, as they heard the hostage taker saying a prayer.

Questions over accomplices
It is still not clear whether the supermarket gunman, 32-year-old Amedy Coulibaly, had an accomplice or not. Police had earlier issued an appeal saying they were looking for Coulibaly and a 26-year-old woman called Hayat Boumeddiene after both were suspected of involvement in the fatal shooting of a policewoman in a southern Paris suburb on Thursday.
Police are still actively searching for Ms Boumeddiene, whose whereabouts remain unknown. Several old photos of the two have been published on Le Monde's website, some of which show them both firing a small crossbow.

What were the indications?
Security services could not hope to keep close tabs on everyone with terrorist sympathies, but there were important questions to be asked nonetheless, the Royal United Services Institute's Shashank Joshi tells the BBC.
"The question isn't so much 'did they slip through?' - they certainly did - but what were the indications? Were there any indications they were acquiring weaponry, for example; that is a failure. They built up a weapons cache; there are some indications their neighbours knew about the weapons cache. The failure to have forewarning of that is a failure, but I think it is important to remember that there are hundreds and hundreds, if not thousands of people on these lists. No intelligence agency can track them all."

"I just had the time to throw myself under a small table in a small recess. I was crouching there and saw my colleagues lying on the ground. I was lucky that the room was so small the gunman could not easily walk around the table to look behind it. There was a long silence, then I heard him step away. As he left I heard him tell a woman in the newsroom: 'We don't want to kill women.' He then exchanged a few words with another man and that's when I realised that they were two."

Roger Carter emails: I see no justification for the killing of these journalists but think it wrong of some newspapers to republish the original offending images of Mohammed as an apparent act of defiance. The fact remains that Charlie Hebdo chose to ridicule the faith of several million people, the vast majority of whom are neither 'extremists' nor terrorists. Attacking Islam can't be the way to fight terrorism and it will only widen the divisions in our society.

France outraged - but not yet divided
BBC Special Correspondent Fergal Keane has filed a report from the banlieue, or suburb, where one of the Charlie Hebdo gunman lived.
He says that for many in France, the word banlieue is "often loaded with negative association".
"In the minds of some French, these estates can be breeding grounds for radicalism," he adds.
"France is outraged but not yet polarised between Muslims and the rest. That isn't to underestimate the potential for a much wider crisis.
"Muslim elders say the key to tackling the problem is breaking the power of radical Islam among the alienated young."
Al-Qaeda group 'praises attack'
Al-Qaeda's branch in North Africa has praised the attack on the office of Charlie Hebdo, according to an organisation which monitors jihadi activity.
Site Intelligence Group said that al-Qaeda in the Islamic Maghreb (AQIM) had also issued a reminder that Osama Bin Laden, al-Qaeda's founder, had threatened those who mocked the Prophet Muhammad

90 witnesses come forward; autopsies completed
Bernard Cazeneuve, the French interior minister, has given more details on the manhunt:
"Interpol has been alerted. Some men were spotted in Villers Cotterets this morning [where the Kouachi brothers are thought to have been sighted earlier]. The national police have acted in various places so as to arrest some suspects.
More than 90 people came forward as witnesses, several of them repeated words that have been uttered by the criminals. The post mortems of the victims have been done, and surveillance on the roads are being examined as well.
An anti-terrorism plan is being put into place and powerful means are being put together at the disposal of the police. Also I have invited in Paris on Sunday my colleagues from other European countries that are concerned, including Greece and the United States. It is also an opportunity, they tell me, to show solidarity with France."

Benoit Verdun, a hotel worker, told Sky News: "There are lots of policemen. I can see a huge police car. They are asking people 'have you seen anybody?' They have big guns with them. The forest is bigger than Paris - it is very big and very wide. "
'Calm person'
Eric Bade, the neighbour of Cherif Kouachi, one of the suspected attackers, says he had not behaved in a suspicious way before.
He tells the BBC that Cherif was "well-behaved, friendly, polite, clean-looking and above all, which is very important, he was willing to help old people and disabled people. Very willing to help... he wasn't aggressive. He wasn't a crazy zealot. He was a calm person."
Police have been closely guarding this petrol station near the town of Villers-Cotterets, 50 miles (80 km) from the French capital, since reports that the Charlie Hebdo suspects had carried out an armed robbery there.

Latest PostPost update
We're bringing to an end our live coverage of the dramatic near simultaneous police raids that resulted in the killings of the two Charlie Hebdo suspects and a third gunman who took several people hostage at a supermarket in eastern Paris.
France is continuing to mourn for the Charlie Hebdo victims, as well as four of the hostages killed during Friday's supermarket siege. You can follow further updates, as well as background material on the story, on the BBC News website.
Asterix is Charlie
Perhaps France's best-know cartoonist has shown his solidarity too. Albert Uderzo, who co-created Asterix, released these two images telling Le Figaro he wanted to show his "affection" for the cartoonists who had died.

Ian Benton emails: We live in the Marais 5 minutes walk from the Charlie Hebdo offices. We are British/American with our little 24 month old boy and expecting our little girl in May. Paris is a big but small city so wherever you live it is close to what is happening. This is also why Paris will always rebound stronger and more unified as the community spirit is what really makes it the city of lights. Vive la France :-)
Police video of raid
Another video released by French police shows the moment special forces launched a raid on the print workshop in Dammartin-en-Goele, where the Charlie Hebdo suspects were hiding out.
Dramatic footage
Amateur footage broadcast by France2 TV shows the storming of the supermarket. The shop shutters open slowly to reveal a body lying as police quickly approach the entrance. They fire into the building.
The shot is frozen when a man dressed in black - possibly the hostage taker - appears running towards the door. Dozens of police enter the supermarket and hostages run onto the street. A body is then seen being dragged out of the shop. It is not clear whether it is that of the gunman.

The positive in this is the reaction and unity my fellow citizens have shown and also the support felt from abroad.

In an earlier entry, we told you how the Arc de Triomphe has been lit up to say "Paris is Charlie" - there is a similar message of solidarity in Toulouse.

Francois Molins, Paris Prosecutor
Police were able to identify Coulibaly's DNA from a cloth found near the scene of the deadly attack on a policewoman in Montrouge on Thursday. He was identified within two hours.
Francois Molins, Paris Prosecutor
It is likely four of the hostages were killed when the gunman entered the Jewish supermarket, and not during the special police operation that ended the siege. The gunman had called a TV station to say that he had killed four of the hostages.
Francois Molins, Paris Prosecutor
Coulibaly and his girlfriend, Hayat Boumeddiene, spoke more than 500 times to the Kouachi brothers over the phone.
Printing works employee 'hid'
Paris prosecutor Francois Molins, speaking at a conference, says that an employee at the printing works where the Kouachi brothers were in Dammartin-en-Goele, was hiding on the second floor underneath a sink. The brothers did not realise there was another person hiding in the warehouse.

Kouachi brothers' neighbours 'found weapons'
The Globe and Mail's Mark Mackinnon tells BBC Newshour that he met a Tunisian woman who was living next door to one of the Kouachi brothers.
"She had been concerned about her neighbours for quite some time, and described how she heard the brothers praying loudly through the walls. She thought they may be extremists so her husband broke in with the help of a plumber and discovered a cache of weapons. The brothers caught them, and forced them to promise not to tell the police."
Police 'heard gunman praying'
According to French media, police were able to monitor what was happening inside the supermarket when the gunman, Amedy Coulibaly, failed to hang up properly after speaking to them. The BFMTV news channel says this was what enabled the police to hear what was going on in the background, as they heard the hostage taker saying a prayer.
Post update
Forensic experts are still investigating the hostage site at the Jewish supermarket as night-time draws in.
Questions over accomplices
It is still not clear whether the supermarket gunman, 32-year-old Amedy Coulibaly, had an accomplice or not. Police had earlier issued an appeal saying they were looking for Coulibaly and a 26-year-old woman called Hayat Boumeddiene after both were suspected of involvement in the fatal shooting of a policewoman in a southern Paris suburb on Thursday.
Police are still actively searching for Ms Boumeddiene, whose whereabouts remain unknown. Several old photos of the two have been published on Le Monde's website, some of which show them both firing a small crossbow.

What were the indications?
Security services could not hope to keep close tabs on everyone with terrorist sympathies, but there were important questions to be asked nonetheless, the Royal United Services Institute's Shashank Joshi tells the BBC.
"The question isn't so much 'did they slip through?' - they certainly did - but what were the indications? Were there any indications they were acquiring weaponry, for example; that is a failure. They built up a weapons cache; there are some indications their neighbours knew about the weapons cache. The failure to have forewarning of that is a failure, but I think it is important to remember that there are hundreds and hundreds, if not thousands of people on these lists. No intelligence agency can track them all."

I was lucky that the room was so small the gunman could not easily walk around the table to look behind it. There was a long silence, then I heard him step away. As he left I heard him tell a woman in the newsroom: 'We don't want to kill women.' He then exchanged a few words with another man and that's when I realised that they were two."

"In the minds of some French, these estates can be breeding grounds for radicalism," he adds.
"France is outraged but not yet polarised between Muslims and the rest. That isn't to underestimate the potential for a much wider crisis.
"Muslim elders say the key to tackling the problem is breaking the power of radical Islam among the alienated young."
Al-Qaeda group 'praises attack'
Al-Qaeda's branch in North Africa has praised the attack on the office of Charlie Hebdo, according to an organisation which monitors jihadi activity.
Site Intelligence Group said that al-Qaeda in the Islamic Maghreb (AQIM) had also issued a reminder that Osama Bin Laden, al-Qaeda's founder, had threatened those who mocked the Prophet Muhammad

Nine now in custody
The French Interior Ministry has confirmed nine people are now in custody in connection with the Charlie Hebdo shooting.
Paris steps up security
Mr Cazeneuve also told the press conference that security has been stepped up across Paris. He mentioned police mobilisations around the headquarters of some media outlets, places of worship and religious schools, stations, schools and diplomatic representations as well as tourist sites. Transport security has also been intensified, he added.
90 witnesses come forward; autopsies completed
Bernard Cazeneuve, the French interior minister, has given more details on the manhunt:
"Interpol has been alerted. Some men were spotted in Villers Cotterets this morning [where the Kouachi brothers are thought to have been sighted earlier]. The national police have acted in various places so as to arrest some suspects.
More than 90 people came forward as witnesses, several of them repeated words that have been uttered by the criminals. The post mortems of the victims have been done, and surveillance on the roads are being examined as well.
An anti-terrorism plan is being put into place and powerful means are being put together at the disposal of the police. Also I have invited in Paris on Sunday my colleagues from other European countries that are concerned, including Greece and the United States. It is also an opportunity, they tell me, to show solidarity with France."

He tells the BBC that Cherif was "well-behaved, friendly, polite, clean-looking and above all, which is very important, he was willing to help old people and disabled people. Very willing to help... he wasn't aggressive. He wasn't a crazy zealot. He was a calm person."

Ross Douthat, blogger and New York Times columnist, has written a widely shared opinion article, arguing that blasphemy is necessary in order to strengthen what he calls liberal civilisation.

To deny the right to laugh from the idea is an attempt to limit how people think, it is attempt to make people think the same way… and I'm sorry but that is unacceptable. Monty Python's Life of Brian might have aroused a discussion, but I don't think any Christians took machine guns and went out hunting the actors. This is an example of our values and I agree that as a sign of unity all newspapers should publish some cartoons!
