Monday morning - rush hour - the busiest London Bridge ever gets.

At the best of times the landmark is choked with workers going about their own business - but this Monday morning, most took a moment to glance at the aftermath of the devastation which unfolded just steps away from their offices.

Reporters from around the world were stationed in front of the cordon, too, gently questioning some of those who took a minute to pay their respects.

Street corners were covered in flowers, cards and posters - a floral tribute to the people who lost their lives in Saturday's attack.

"London Bridge will never fall down" and "London United" were the overriding messages rippling through the borough.

The people of London and visitors - although quiet in thought - were strong and mainly carrying on with life as normal.

Theresa May says the UK's counter-terrorism strategy must be reviewed after Saturday's attack.

With three terror incidents in just three months, the NHS must be primed for any eventuality.

Dr Malcolm Tunnicliff, clinical director of the emergency and acute care department at King's College Hospital in south London, said eight of those injured were still critically ill.

Hedieh from Los Angeles is on holiday in London with her family.

This morning police carried out raids at a property in Dagenham.

James Bateman, who lives at the other side of the road, said: "At about 4am, after the large bang, I looked outside the window after being woken up and I saw about a dozen armed police officers going to and from an unmarked van."

He said they were wearing "full gear", adding: "The first bang was nothing like I'd heard before."

Transport for London says all entrances and exits to London Bridge Underground station have now reopened, with the exception of Borough High Street.

The station, which closed following the attack on Saturday, is operating a normal service but it may be busier than usual.

BBC political editor Laura Kuenssberg asked the prime minister if reversing cuts to police numbers would show greater leadership. She also says that the most direct experience members of the public have that they are being kept safe is by seeing police officers on the streets - and says that control orders for monitoring terrorists had been "watered down".

Theresa May replies, saying control orders had been knocked down in the courts, which is why she had ensured the police had powers within their remit to ward against "people who will do us harm".

She said the government had funded an increase of 1,500 armed officers, adding "it's not just about the resource but the powers the people have".

In a further question on police cuts, Mrs May says she does believe "a more robust approach" needs to be taken to deal with extremism in this country

While progress has been made in counter terrorism, "I think we've seen too much tolerance of extremism in our society so we do need to deal with it".

This is why the UK will be the first country to introduce a commission on countering extremism, she says, adding that this will work with the public sector, civil society, organisations and individuals to help people identify extremism.

"I believe that will help us in that necessary task of stamping out extremism," she said.

Hospitals in London have increased their security measures following the terror attack on Saturday night.

Guy's and St Thomas' NHS Foundation Trust said it is operating "with enhanced security".

Nine victims of the attack were taken to the emergency department of St Thomas' hospital - which is situated on the south side of Westminster Bridge.

In a statement on its website, Guy's and St Thomas' NHS Foundation Trust said: "We are operating with enhanced security, but services are running as normal.

"Please attend appointments as planned, but bring your appointment letter and photo ID. Allow more time to travel."

Imperial College Healthcare NHS Trust urged patients and visitors to be "vigilant".

In a statement on its website, the trust said: "Following the incidents at London Bridge and Borough Market, our own security team will be stepping up their presence on our campuses.

Theresa May says the Met Police shoot-to-kill policy had "saved countless lives" during Saturday's London Bridge terror attack.

The prime minister was defending her record as a former home secretary following Labour's accusation that while in the post she was responsible for a cut in police numbers.

Mrs May said she supported the shoot-to-kill policy "absolutely", adding: "Those police officers within eight minutes had shot the three attackers and killed them and that saved countless lives."

She said that Met Police chief Cressida Dick had said her force was well resourced, adding that the government had protected counter terrorism policing budgets, funded an uplift in number of armed officers and protected police budgets.

"I've been responsible for giving police extra powers for dealing with terrorism - and Jeremy Corbyn has boasted that he has opposed those powers," she added.

A man who knew one of the London attackers has told the BBC he reported him to the anti-terrorist hotline two years ago.

Daniel Sandford, the BBC's home affairs correspondent, says the Metropolitan Police has acknowledged there is a need to reassess how it deals with counter-terrorism following the growth in people using less sophisticated weapons to kill - such as driving vehicles and using knives.

He said: "There is some satisfaction here at Scotland Yard that when this attack happened on Saturday night, it was dealt with quickly, swiftly and aggressively."

But he says the big question facing the police is: "'How do we now try to intercept these very simple attacks further up the line?' and I don't think anyone really has the answer to that at the moment."

Romanian baker Florin Morariu has been described as a hero on social media.

The man, who works at Bread Ahead bakery in Borough Market, saw a commotion outside the shop on Saturday evening.

He invited some distressed Brazilian women into the shop and gave them a glass of water. They explained that three men were stabbing revellers in the market.

He said he grabbed two crates and went outside to find the attackers and defend the injured.

Speaking to the Victoria Derbyshire show, he said: "I felt pity for the victims, I didn't know how to handle things or react, I thought to myself I'm also in danger.

"I just threw the crate at [one of the attackers]. I threw the first crate and I knew he was going to dodge it. While he was dodging it I walked towards him and hit him in the head with the other crate."

He then said a policeman shouted at him to stand back.

The officer then discharged a grenade.

Labour leader Jeremy Corbyn is making a campaign speech in a rainy Middlesbrough, and starts by remembering the victims of terrorist attacks.

"Four people from this region died at the concert in Manchester," he says, and also remembers "those who have been killed just because they were out on a Saturday night enjoying themselves" in London.

He describes Sunday's concert in Manchester as "absolutely the right thing to do", adding: "We are not going to allow anybody to dictate how we live our lives or how we go about enjoying ourselves."

Looking ahead to the election: he says: "We carry on. Democracy will prevail."
