As Londoners start to process and reflect on the tragic events of Saturday night, near London Bridge, crowds at tribute concert One Love Manchester have sent a message of solidarity with the capital.

The gig was organised by Ariana Grande after 22 people were killed by a suicide bomber at the end of her concert at Manchester Arena on 22 May.

Speaking on stage at the event, Mayor of Greater Manchester Andy Burnham said he wanted to send a message to "our friends in London who are going through the same as we were going through".

"We know how you are feeling but we will stand with you and we will get through this together," he added.

"On days like today it's hard to find words to express how we're feeling.

"The simple fact is your presence here tonight says more than 1,000 words ever could, so a huge thank you to you all for being here."

Here's a rundown of what has happened since Saturday evening:

• Seven people have been killed, 48 were injured, and 36 remain in hospital
• Police have arrested 12 people - 11 of them at a single address in Barking - as investigations continue.
• All those arrested are being held under the Terrorism Act

• So-called Islamic State has claimed responsibility for the attack encrypted messaging app Telegram
• During the incident, a member of the public was shot by police, but is not in a life-threatening condition
• Cordons are still in place in the area around London Bridge, though police hope to reopen some areas on Monday morning
• Borough station has reopened, and commuters are encouraged to check TfL transport alerts for information on the London Bridge area

• There will be a minute's​ silence held across the UK at 11:00 BST on Tuesday

Paul Nuttall says the spreading of Islamist ideology by countries like Saudi Arabia and Qatar is what is fuelling radicalisation, not his party's rhetoric.

He also tells a BBC election questions audience restarting the election campaign today sent a "great" signal about British democracy.

UKIP leader Paul Nuttall tells a BBC election questions audience banning the burka would aid integration and would, for example, help Muslim women find work.

He says UKIP's policies are "all about integration".

Questioned about grooming gangs, Paul Nuttall says: "Because of political correctness we have turned a blind eye."

He adds: "Religion and race in these circumstances should be an aggravating factor when these cases go to court."

UKIP leader Paul Nuttall tells a BBC election questions audience says we can "no longer turn a blind eye" to Islamism.

"I was glad to hear Theresa May today finally say 'enough is enough'".

The answer is more police, more border guards and prison officers to "ensure our own people are safe".

Only one-in-eight referrals to the government's Prevent programme come from within the Muslim community, says UKIP's leader as he takes the stage in the BBC's election questions programme.

He adds: Islamism is not Islam, it is not about not Muslims - Islamism is a political ideology, an ideology of violence."

"The Green Party would end commercial arms sales to Saudia Arabia," says co-leader Jonathan Bartley on a BBC election questions programme.

Green co-leader Jonathan Bartley says most Muslims "hate" terrorism, and he does not accept audience members' claims that many Muslims support it.

"This is not a problem that Muslims have to deal with, it's a problem we all have to deal with."

London Bridge rail station will re-open on Monday morning, staff have confirmed.

Police cordons will still be in place until at least 8am though, so it will be exit only until they are lifted.

There are also warnings that disruption is expected because of restricted access, so the station will be busier and a queueing system may be put in place.

The advice for commuters is to avoid the station if they can.

The bridge itself and nearby roads are also expected to be hit by closures.

Jonathan Bartley warns against "knee-jerk reactions" and says his "instinct" is "not to arm all our police".

But he adds that that we should wait for the outcome of the review, saying "let's see what happens".

Green co-leader Jonathan Bartley echoes Jeremy Corbyn's criticisms of cuts to police numbers, saying they threaten the British tradition of community policing and "policing by consent".

He repeats his criticism of Prevent, saying it is "xenophobic".

Jonathan Bartley says Theresa May is right to review the way the UK deals with Islamist terrorism.

But he says the UK's counter-radicalisation strategy Prevent should be scrapped.

"It is clearly toxic to some communities," he tells the BBC election special audience in Bristol.

"It is alienating some communities and therefore we are not getting to the root of radicalisation, not building bridges we need. We are not getting the intelligence that we need."
