A poignant video from Manchester, where the Ariana Grande-led memorial concert has just fallen silent to remember those killed in London.

Facebook has followed Google in issuing a statement in the wake of the London attack and British Prime Minister Theresa May's call for internet regulation.

It said it wanted to make its social media platform a "hostile environment" for terrorists.

May has demanded greater international regulation of the internet, saying big internet companies were partly responsible for providing extreme ideology the space to develop.

Facebook on Sunday said it condemned the London attacks.

"We want Facebook to be a hostile environment for terrorists," said Simon Milner, Director of Policy at Facebook in an emailed statement.

"Using a combination of technology and human review, we work aggressively to remove terrorist content from our platform as soon as we become aware of it – and if we become aware of an emergency involving imminent harm to someone's safety, we notify law enforcement."

May has previously put pressure on internet firms to take more responsibility for content posted on their services. Last month she pledged, if she wins an upcoming election, to create the power to make firms pay towards the cost of policing the internet with an industry-wide levy.

The Eiffel Tower will turn off its lights in Paris tonight in solidarity with the people of London.

The UK government has announced there will be an official minute's silent across the UK at 11am on Tuesday. Flags will fly at half mast until Tuesday evening.

Meanwhile in Manchester, a star-studded benefit concert spearheaded by Ariana Grande and in memory of the victims of the attack there two weeks ago is going ahead as planned.

Manchester mayor Andy Burnham said he has sent a message of support to Sadiq Khan, London's mayor, saying he knew what he was going through.

He said during the day he had become more and more of the view the concert should go ahead.

"What's the alternative, we give up we become hateful and fearful of each other?" he said.

"We should carry on to live our lives as we want to."

He said he stood ready to work with PM Theresa May, in a cross-party effort to calibrate the right response to the London attack.

French Foreign Minister Jean-Yves Le Drian has confirmed that one French national was killed in London on Saturday night. 

Seven other French people are still in hospital – four in a serious condition. He said one other French national was still missing.

A man pictured calmly taking his pint of beer with him as other people fled past him during the attack has been cast as an unlikely hero who encapsulates British humour and defiance.

Dressed in a red T-shirt and sauntering casually with a friend, the drinker stood out in footage of men and women running down Borough High Street on Saturday night.

The image spread like wildfire across Twitter and British newspapers said the man, whose identity is unknown, was a symbol of defiance.

Londoners take pride in, and sometimes joke about, showing fortitude during adversity.

Tourist shops are awash with memorabilia emblazoned with "Keep calm and carry on", a slogan drawn from a World War II poster that as become popular in the last 10 years.

Further to our earlier post about British PM Theresa May calling on internet companies to do more to fight terrorism (Google released a statement saying it was already working to do its part) ...

Carl Bildt, former Swedish prime minister and foreign minister, has poured scorn on May's plan to regulate internet giants to eliminate online "safe spaces" for extremists.

In her response to the attack, the UK prime minister said "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.

"We need to work with allied, democratic governments to reach international agreements that regulate cyberspace to prevent the spread of extremism and terrorist planning. And we need to do everything we can at home to reduce the risks of extremism online."

But Mr Bilt tweeted: "I'm sure China, Russia, Iran and some others will applaud Theresa May's intention to control and limit the internet."

Policing levels in the UK are likely to become a hot issue following the London attack. 

The UK election is scheduled for Thursday and Opposition Labour Leader Jeremy Corbyn has made an increase in police numbers central to his campaign.

Here is a Manchester police officer telling Prime Minster Theresa May (who was then Home Secretary) at the 2015 National Police Conference that government cuts to the police budget would increase the risk of terrorism. The budget cuts went ahead. 

 

Google says it's committed to ensuring terrorists "do not have a voice online". 

British Prime Minister Theresa May was on Sunday critical of internet companies and social media outlets for providing "safe" places for terrorism to breed.

Brits have taken to Twitter in response to a New York Times headline that said the recent terror attacks in Manchester and London had left the UK "reeling".

The subsequent #ThingsThatLeaveBritainReeling hashtag is currently out-trending #LondonAttacks and other tags relating to the London Bridge attacks on Saturday night.

Here are some of the responses.

Mark Rowley, head of the Metropolitan Police's counter-terror operations, has given an update.

He says:

• Eight firearms officers shot at the attackers, firing about 50 bullets – which he called an unprecedented number. They killed the terrorists, but also wounded one member of the public, who is in hospital but not in a critical condition.
• He defended the officers' bullet count, saying it was a critical situation, with three armed men who appeared to be wearing suicide belts. There will be a routine investigation into the use of the weapons.
• Police are still working to inform the next of kin of the 7 people killed by the terrorists. "Some of the victims" were from abroad, he said.
• Some 36 people remain in hospital with a range of injuries, some extremely serious. He said 21 are in a critical condition.
• Police are "increasingly confident" the three men were the only ones involved in the attack, but were still working to establish whether anyone else was involved in the planning.
• Searches are ongoing in East London.
• He "was not in a position" to name the attackers.
• There will be a high security presence on London's bridges in the next few days.

Barking resident Ken Chigbo told Sky News one of the men believed to be behind the attack had asked about hiring a van from him the day before the incident.

"I'm moving house at the moment, so I had a big van outside," Mr Chigbo said.

"He's usually a very nice friendly guy. But this time it was on a different level of nice.

"[He asked] all these specific questions about the van, which obviously now makes sense in my head. At the time, I didn't think anything of it."

Canadian Prime Minister Justin Trudeau has confirmed a Canadian was among those killed in the London attack.

"Canada strongly condemns the senseless attack that took place last night in London, United Kingdom, which killed and injured many innocent people. I am heartbroken that a Canadian is among those killed," Trudeau said in a statement.

He had earlier tweeted support numbers for nationals. 

Witnesses have described hearing shots as police arrested several people in connection with the London Bridge terror attack on Sunday morning.

Residents said armed officers swooped on flats in Barking, in London's east, where they believe one of the attackers may have lived.

Further raids are currently taking place in East Ham, also in East London as I type.

Veronica Oladapo, 45, who lives in an apartment block neighbouring the Barking raids, left her building at around 7am to see police taking four men and a woman away.

"When I came out they were already taking some of the casualties away," she said. "There were three of them ... the ambulance came and took them away.

UK Prime Minister Theresa May has announced a new push to deny extremists their "safe spaces" both online and in the real world. 

"Enough is enough," she said outside 10 Downing Street.

Full details here.

Fairfax Media's Nick Miller is reporting from London.

He says the investigation is "progressing rapidly", according to the Metropolitan Police Service.

On Sunday morning, police carried out a series of raids in Barking, east London, arresting 12 people in connection with the attack on London Bridge and the Borough Market area. 

Searches of a number of addresses in Barking were ongoing.

Nick's latest report is here.
