On Twitter, users have been reminding users in other countries that the city has a history of continuing daily life - by publishing archive photos from the World War Two bombing campaigns.

Mike Haines, whose younger brother David Haines, 44, was beheaded in Syria in 2014, said: "From my own loss, I know first-hand the hurt and anger that many people are feeling today

"While it is hard at a time like this, I also know that hate can never be the answer - that is what the terrorists want, and it is not what we as a country are about," he told the Press Association.

A call by Prime Minister Theresa May to regulate tech firms in the wake of the London attacks has been criticised.

She said areas of the internet used by terrorists must be shut down.

But Open Rights Group - an organisation campaigning for online privacy and free speech - said more regulation could push "these vile networks into even darker corners of the web".

"The internet and companies like Facebook are not the cause of hate and violence, but tools that can be abused," the digital rights group said, while condemning Saturday's attack on the London Bridge area.

The Muslim Council of Britain has condemned Saturday's attack.

The Council's Secretary General Harun Rashid Khan told Newshour that he was "appalled and angered" by the attack.

The leader of the UK Independence Party has said the country must "fight fire with fire" when it comes to tackling Islamic extremism.

Paul Nuttall was asked if he agreed with Theresa May's statement that the UK has been "tolerant" of extremism, and he said: "Yes we have. The fact that we haven't been prepared to name it - or the main party leaders haven't - up until today is just proof.

"We've got to get real now. These people are a clear and present danger to our own people in this country. As I've said before, we've got to fight fire with fire. I wouldn't take anything off the table in dealing with these people."

Another neighbour of a suspected attacker, who lives in the same flats in Barking, said he saw him as a family man.

"We have a good relationship with all the neighbours around us," said the resident. "We know every single one, it is like a family.

"I saw him with the kids, always around with the family, joking."

But the neighbour said he had seen him at the local mosque disagreeing with the Imam in a middle of a service.

“People said to him don’t interrupt, come back later and asks the questions," he added, "But he didn’t agree with that and people took him out.

“I was shocked. I can’t believe that is the person."

Donald Trump rang Theresa May to offer his condolences and support. But in a flurry of tweets, the US President also used the attack to renew his demand for a ban on travellers from six mostly Muslim countries.

He also appeared to criticise the Mayor of London Sadiq Khan for saying there was no need to be alarmed.

In fact, Mr Khan was urging people not to be worried by the increased police presence. A spokesman said the mayor had more important things to do than respond to Mr Trump's ill-informed tweet.

Other world leaders used twitter largely to offer their solidarity and sympathy, particularly those with nationals injured or killed in the attack.

President Macron of France spoke to Mrs May and reminded her of the importance of European cooperation in the fight against terrorism.

President Putin of Russia called for a joint effort in the fight against the forces of terror.

And in Rome, the Pope led prayers for peace.

In the absence so far of a claim of responsibility for the London attack, online supporters of Islamic State group (IS) have continued to celebrate the vehicle and stabbing incidents, urging others to carry out more assaults.

A channel on the messaging app Telegram, called "Just Terror" that had been launched after the London attack, addressed "IS soldiers everywhere" telling them "it is not difficult" to do something similar.

Meanwhile a small number of al-Qaeda supporters on Telegram also praised the London attack.

One prominent supporter of the group said "news from London gladdens the heart".

Twitter has responded to Theresa May's call to regulate technology firms in the wake of the London attack.

"We cannot allow this ideology the safe space it needs to breed," the prime minister said earlier. "Yet that is precisely what the internet, and the big companies... provide."

But Nick Pickles, UK head of public policy at Twitter, said: "Terrorist content has no place on Twitter."

"We continue to expand the use of technology as part of a systematic approach to removing this type of content.

"We will never stop working to stay one step ahead."

A resident of the block which was raided earlier today in Barking has said the man who lived there was "a bit different".

Asim Uddin said he had known the suspected attacker for around three years as most people moved into the block at the same time.

“He was a bit different... I would say he was not normal," Mr Uddin told the BBC.

"He used to park here in our parking bays and I stopped him. He then said, 'You know what? You should always go against the system.'"

Mr Uddin also described him as a "hyper type of person" who was easy to identify.

“He was different, but I never knew he had extreme views. He didn't showed any of that," he added.

Reverend Jide Macauley said: "We're here to provide visibility, walking from Bermondsey and around London, talking to people and having a presence at the scene.

"We're from the faith community and we wanted to show presence and a communication with our Muslim brothers and sisters.

"Incidents like this are blamed on religion and they shouldn't be.

"We come to love in the name of God and Allah.

"Politics is not the be all and end all. We were moved by the principle of love. We're holding families in hearts and minds.

"It breaks my heart for this to happen in the city that I love."

Armed police have raided another flat in east London and taken two people away, according to witnesses.

Locals told the Press Association that they had seen dozens of officers carrying guns, with their faces covered, entering a property above a shop in East Ham at around 2pm on Sunday.

Witnesses say two men were dragged out and taken away in police vans.

Resident Malik Rouf, 30, said one of the men inside the flat jumped out of a first floor window on to a ledge before he was pulled back inside.

Shimma Ali, 32, said: "I heard a woman screaming and 20 officers with guns - there was a sniper across the road trained on the window.

"It's absolutely terrifying - we don't expect it in this area, it's so multicultural and diverse, there's no racism."

Police have now put up a cordon around the house, with officers guarding the perimeter.

Calls to scrap the government's Prevent strategy are "naive, opportunistic and endangers our national security", according to the founder of anti-extremism think tank Quilliam.

Maajid Nawaz said any politician calling for the end of the scheme "does not understand extremism, nor the severity of the jihadist terror threat that is facing us".

Prevent is a government programme aiming at deradicalising young people or stopping them from becoming radicalised in the first place. It has faced criticism from some commentators for demonising the Muslim community.

Quilliam chief executive Haras Rafiq added: "Enough is enough - we need action now and not tip-toeing around the issue.

"The only way to defeat this type of extremism and terrorism is for government and all British communities to unashamedly name, shame and challenge the threat. That includes the ideology that is underpinning it."

Former UKIP leader Nigel Farage has told US channel Fox News, where he works as a contributor, he thinks the British public will start demanding internment - or imprisonment without charge - of terror suspects unless the government "gets tough" in its response the London attacks.

At the end of a segment on the mood in Britain, Mr Farage said: "If there is not action, then the calls for internment will grow."

"We have over 3,000 people on a sort of known terrorist list. And we're watching, monitoring their activities," he said.

"Unless we see the government getting tough, you will see public calls for those 3,000 to be arrested."

"I'm not sure that is the right approach," he added. "Because the big danger with that is we might alienate decent, fair-minded Muslims in Britain.

"But whatever happens, we do need action."

People have taken to social media to post pictures of signs and art work bearing defiant messages of solidarity in the wake of the London Bridge attack.

"London Bridge will never fall down" and "I love London" are just some of the slogans being shared alongside the hashtag #prayersforLondon.
