SEVERAL people were detained by police during an armed operation at some east London flats where neighbours said one of the London Bridge attackers may have lived.

At least four police vans were stationed behind a cordon outside the Elizabeth Fry flats in King's Road, Barking, and residents reported hearing bangs on Sunday morning.

Some neighbours said a photograph of one of the attackers resembled a man who lived in one of the flats.

Veronica Oladapo, 45, who lives in the neighbouring Forresters Apartments, said she left her building at around 7am to see police taking four men and a woman away.

She said she saw two men and a woman being taken away by ambulance after other neighbours reported hearing shots fired, while two men were later led away by police.

She said: "When I came out they were already taking some of the casualties away.

"There were three of them ... the ambulance came and took them away.

"There were another two sitting down inside."

One of the men had a hood pulled over his head while another one used a jacket to hide his face, she said.

The raids follow a string of horrific attacks last night after a van ploughed into pedestrians on London Bridge.

Three terrorists exited the vehicle in Borough Market and began stabbing innocent bystanders at random. 

They were shot dead at the scene by police. 

The terrorists were wearing fake suicide belts to spread fear, it has now been confirmed. 

The Prime Minister has vowed that 'enough is enough' after seven people were killed and 48 injured in the third UK terror attack in 10 weeks. 

Speaking outside Downing Street this morning (Sunday), Mrs May said there is 'far too much tolerance' of radical Islam ideology and that measures need to be taken, such as internet laws, to stop the spread of hate. 

The Prime Minister, who was in the north on her campaign trail, returned to Downing Street last night. She will share a meeting of COBRA this morning. 

Mrs May warned that we "cannot and must not pretend that things can continue as they are", saying changes were needed in four areas.

 She said defeating the "evil" ideology of Islamist extremism is "one of the great challenges of our time" but stressed it "cannot be defeated by military intervention alone".

 She threw down the gauntlet to web giants and called for international agreements to regulate cyberspace, saying: "We cannot allow this ideology the safe space it needs to breed - yet that is precisely what the internet, and the big companies that provide internet-based services provide."

 Mrs May also set out her determination to stamp out "safe spaces" that exist in the real world, saying: "There is - to be frank - far too much tolerance of extremism in our country".

The PM said there was a need for Britain's counter-terror strategy to be reviewed to ensure police and security services have all the powers they need, while she also raised the prospect of longer jail terms for terror-related offences, including those which are "apparently less serious".

Mrs May said the UK has made "significant progress" in disrupting plots and protecting the public since the emergence of the threat from Islamist-inspired terrorism.

"But it is time to say 'enough is enough'," she added.

"Everybody needs to go about their lives as they normally would. Our society should continue to function in accordance with our values.

"But when it comes to taking on extremism and terrorism, things need to change."

The major political parties suspended national election campaigning after the attack but Mrs May confirmed the poll would go ahead on Thursday.

She said: "Violence can never be allowed to disrupt the democratic process, so those campaigns will resume in full tomorrow and the General Election will go ahead as planned on Thursday.

"As a country, our response must be as it has always been when we have been confronted by violence.

"We must come together, we must pull together, and united we will take on and defeat our enemies."
