Former Met boss: Attacks will get throughpublished at 08:30
08:30Today Programme
BBC Radio 4Sir Ian Blair, former Metropolitan police commissioner, says "attacks will get through".
He says "it feels like human error" referring to mistakes made by the security services. But he says its the kind of error that can get through anywhere.
He adds "it's not as easy to get here" as the UK isn't part of the Schengen area but says that doesn't mean it won't happen.
Paris attacks: Islamic State militants change tacticspublished at 08:27
08:27Frank Gardner, BBC security correspondent says...
Friday's Paris assaults mark a new and frightening watershed in the steady expansion of attacks attributed to or claimed by the so-called Islamic State.
For most of last year and much of this, IS's focus has been on taking and holding territory in the Middle East. For its leaders in Raqqa and Mosul, that is still the priority.
But the militants are well aware of their transnational appeal to violent jihadists in Europe and elsewhere.
As they reel under the daily onslaught of US-led coalition airstrikes, haemorrhaging one leader after another, they are increasingly looking to direct or inspire attacks further afield.
Cameron urges 'resolve' after attackspublished at 08:22
08:22The British public must show "resolve" and "carry on with our lives" in the wake of the terror attacks on Paris, Prime Minister David Cameron says.
It comes as extra funding for the UK's security services has been announced by the government, to help combat the threat from Islamic State militants.
The money will allow MI5, MI6 and GCHQ to recruit an extra 1,900 officers.
Mr Cameron told the BBC he was hopeful of an agreement with Russia over the future of Syria.
Paris attacks: Fighting IS at home and abroadpublished at 08:18
08:18Jonathan Marcus, BBC diplomatic and defence correspondent...
French President Francois Hollande has spoken of waging "a pitiless war" against those responsible for the latest horrors in Paris. The rhetoric is strong. Security has been stepped up. Troops have been drafted in.
But the weekend's bomb attacks and shootings have highlighted once again the difficulties in providing total security in a modern, open Western capital.
But to what extent was there a lapse in security? Might or even should the French intelligence services have stopped this attack?
And what about the broader campaign against the so-called Islamic State (IS) abroad? Is anything likely to change there in the wake of the murderous carnage on the streets of the French capital?
Paris attacks: Who were the victims?published at 08:14
08:14Information about the 129 Paris terror victims has started emerging.
French Prime Minister Manuel Valls said on Sunday that 103 bodies had been identified from Friday's attacks, with 20 to 30 more still awaiting identification.
"They will be (identified) in the coming hours," said Mr Valls.
At least 23 foreigners were among those killed in the attack, the AFP news agency reports.
Paris attacks: 'Planned from Syria'published at 08:12
08:12Friday's attacks by Islamist militants in Paris were planned and organised from Syria, French Prime Minister Manuel Valls has said.
He added that the authorities believed new terror attacks were being planned in France and other European countries.
Mr Valls also confirmed that raids on suspected militants had been carried out across France early on Monday.
A total of 129 people died in the attacks on bars and restaurants, a concert hall and the Stade de France.
Cameron on England v France footballpublished at 08:10
08:10The prime minister has urged people not to stay away from England's friendly football match against France at Wembley on Tuesday evening, saying he would be happy to take his own children to the match.
Reports over the weekend suggested the game would be cancelled following the Paris terror attacks on Friday.
But David Cameron said while people should be vigilant and could not expect "100% security" in a free society, it was "very important that we carry on with our lives".
He told the Today programme:
Quote MessageIn a free society you have the people and the police working together, so remember that. But remember that our freedom depends on showing resolve and carrying on with our way of life - which is exactly what we ought to do."
Asked if he would take his family to the stadium tomorrow evening he said: "Yes I would."
Cameron on talks with Putinpublished at 08:05
08:05Today Programme
BBC Radio 4David Cameron has implied that there could be "compromises" with Russia, in order to find a political solution in Syria. Speaking on the Today programme earlier, the prime minister said while he has "profound disagreements" with President Putin, he will start talks with him today by discussing the thing both men agree about - "which is that ISIL and this radicalised Islamist extremism is just as much a threat to Russia, potentially more of a threat to Russia than it is to Europe".
On the prospect of Britain joining military action against Syria, Mr Cameron said:
Quote MessageI always said it is sensible that we should... but I need to build the argument, take it to Parliament, I need to convince more people. We won't hold that vote unless we can see that Parliament will endorse that action."
Mr Cameron said the UK security forces had foiled seven plots in that last six months, albeit on a smaller scale than the Paris attacks.
