We are wrapping up our live blog coverage of the Finsbury Park attack.
The London Ambulance Service (LAS) has confirmed it took eight people injured in the suspected terror attack to three London hospitals. It did not give details on their conditions.
In total, 60 paramedics were sent to the scene with the first arriving within 14 minutes of the first 999 call.
Peter McKenna, LAS deputy director of operations, said:
Our thoughts are with all of those affected by the incident in Finsbury Park and their friends and family.
We took eight patients to three London hospitals and treated others at the scene for minor injuries.
We were called to the incident at 12:15am (Monday 19 June) and sent over 60 of our medics including ambulance crews, advanced paramedics, specialist response teams and an advanced trauma team from London's Air Ambulance. The first of our medics arrived within 14 minutes of the first emergency call.
We managed the incident in a dedicated special operations centre, and, as always, our priority was to assess patients and ensure that they were treated and taken to hospital as soon as possible.
I'm very proud of all of our staff who responded to this incident alongside our other emergency services colleagues.
Prime Minister Theresa May has arrived at the scene. It comes after she was criticised heavily for not meeting victims or relatives when she first arrived at the scene of the Grenfell Tower fire.
Eve Hartley, from Huffington Post, has this video:
Richard Watts, leader of Islington Council, has issued a statement on the attack:
"The heartfelt thoughts of everyone at Islington Council are with the family and friends of those affected by the dreadful events in Finsbury Park in the early hours of this morning.
"We have been working closely with the emergency services overnight and have spoken to community leaders, Muslim Welfare House and Finsbury Park Mosque to offer any support we can.
"This is a horrifying and appalling attack, which police are treating as terrorism. Terrorist attacks seek to divide us and sow hatred. Finsbury Park is a diverse and open community and our mosques are a vital part of that community.
"We stand in solidarity with the Muslim community and will continue to stand together and support each other. Islington is a vibrant and unified borough: this is our community, and we will not be divided by any terrorist."
Mohammed Kozbar, the chairman of Finsbury Park Mosque, has given a statement at the scene, joined by other religious leaders from the Islington Faith Forum and Labour leader Jeremy Corbyn.
He spoke of how members of different faiths had gathered at Muslim Welfare House on Saturday to mark the one-year anniversary of the murder of Labour MP Jo Cox, who was killed by far-right fanatic Thomas Mair.
He said: "Less than 48 hours later the same area experienced a terrorist attack, aimed at killing Muslim returning home after their Ramadan prayers. Our thoughts and prayers are with the family of the person who died and with all those injured and traumatised by this event. An attack on one faith is an attack on all faith and communities.
"Those who try to divide us and who aim to spread fear, hatred and division will not succeed ...May we stand together in these challenging times."
Kevin Hurley, the former head of the counter terrorism and public order department for the City of London Police, has been speaking about the problems of stopping attacks involving vehicles and of the impact of police cuts.
He told the BBC: "This [investigation] will take some time and is yet another burden on the already strapped resources of police nationally but particularly the Metropolitan Police, who of course are still trying to deal with all of this in the midst of cuts and further planned cuts."
Commenting on a pledge by the Mayor of London Sadiq Khan to increase the number of patrols outside Islamic places of worship, he said: "Well of course that's a nice soundbite but to be quite clear about it, there are more than 500 mosques in London alone and hundreds and hundreds of Muslim centres, so it's simply not realistic to have officers outside all of them.
"And of course this type of attack, people patrolling on the street are completely ineffective. The only way you can stop someone in a vehicle like this is with barriers and being able to shoot them by reacting immediately."
The Welsh van hire company whose vehicle was involved in the suspected terror attack has issued a statement:
We at Pontyclun Van Hire are shocked and saddened by the incident that took place at Finsbury Park last night. We are cooperating fully with the Metropolitan police and our thoughts are with those who have been injured in this cowardly attack.
We will not be making any further statement because of the ongoing police investigation but will continue to assist the police in any way we can.
A police van was spotted outside the hire company's offices near Cardiff earlier today.
More members of the local Muslim community in north London have been speaking out about Islamophobic attacks.
Nasser Alyarimi, 18, says he knows people who worship at the mosque.
He told the BBC: "There's been lots of incidents taking place. Someone I know was thrown down the stairs and had beer poured over her headscarf just because she is Muslim.
"So I'm not surprised that Muslims have been targeted like this. When I'm on a train in my traditional clothes I get lots of looks.
"Islamophobia has definitely increased.
"Only an individual with such low intellect would do this. The thought makes me really sad. I would say don't put religion in the same category as a terror attack."
Scotland's First Minister Nicola Sturgeon has responded to the suspected terror attack.
Like everybody else, I am appalled, horrified and heartbroken at news of another apparent terrorist attack in the heart of London.
This was a senseless and horrific attack on Muslims leaving prayers in a mosque and our attitude and response to that should just be as serious and as steadfast as our response to those who carry out such attacks supposedly in the name of Islam.
Whether extremists and terrorists, who are a tiny minority in our society, are attacking Muslims or attacking in the name of Muslims, all of us must be absolutely resolute that our wonderful, diverse, multicultural society will not be divided, because that's what the terrorists seek to do and we must be absolutely resolute in our determination not to allow them to succeed.
About once a fortnight there's an attack on a mosque in Britain, according to Tell Mama.
The group recorded 100 attacks on mosques between May 2013 and September 2016. Most were vandalism or criminal damage. There were also arson attacks and worshippers being assaulted.
Here is the full speech from Prime Minister Theresa May, who was speaking outside 10 Downing Street earlier today:
This morning, our country woke to news of another terrorist attack on the streets of our capital city: the second this month and every bit as sickening as those which have come before.
It was an attack that once again targeted the ordinary and the innocent going about their daily lives – this time British Muslims as they left a Mosque having broken their fast and prayed together at this sacred time of year.
Today we come together - as we have done before – to condemn this act and to state once again that hatred and evil of this kind will never succeed.
The Government's Emergency Committee, COBRA, has just met and I can set out what we know about what happened, and the steps that we are taking to respond.
Just after twenty-past midnight, the Metropolitan Police received reports that a van had been driven into a crowd of people on Seven Sisters Road in Finsbury Park.
Officers were in the immediate vicinity as the attack unfolded and responded within one minute.
Police declared it a terrorist incident within eight minutes.
One man was pronounced dead at the scene; eight injured were taken to three separate hospitals; while two were treated at the scene for more minor injuries.
The driver of the van - a white man aged 48 - was bravely detained by members of the public at the scene and then arrested by police.
The early assessment by the police is that the attacker acted alone.
Our thoughts and prayers this morning are with the family and friends of the man who died and those who were injured.
On behalf of the people of London – and the whole country – I want to thank the police and the emergency services once again for responding as they always do with great professionalism and courage.
Extra police resources have already been deployed to reassure communities, and the police will continue to assess the security needs of Mosques and provide any additional resources needed, especially during this final week before Eid Al-Fitr, a particularly important time for the whole Muslim community.
This was an attack on Muslims near their place of worship. And like all terrorism, in whatever form, it shares the same fundamental goal.
It seeks to drive us apart; and to break the precious bonds of solidarity and citizenship that we share in this country.
We will not let this happen.
When I stood here for the first time as Prime Minister last Summer I spoke about our precious belief in the Union – not just the bond between the four nations of the United Kingdom – but the bond between all our citizens, every one of us, whoever we are and wherever we are from.
At the heart of that bond is a belief in the fundamental freedoms and liberties that we all cherish; the freedom of speech; the freedom to live how we choose and yes, the freedom to practice religion in peace.
This morning we have seen a sickening attempt to destroy those freedoms; and to break those bonds of citizenship that define our United Kingdom.
It is a reminder that terrorism, extremism and hatred take many forms; and our determination to tackle them must be the same whoever is responsible.
As I said here two weeks ago, there has been far too much tolerance of extremism in our country over many years – and that means extremism of any kind, including Islamophobia.
That is why this Government will act to stamp out extremist and hateful ideology – both across society and on the internet, so it is denied a safe space to grow.
It is why we will be reviewing our Counter-Terrorism strategy and ensuring that police and security services have the powers they need.
And it is why we will establish a new Commission for Countering Extremism as a statutory body to help fight hatred and extremism in the same way as we have fought racism – because this extremism is every bit as insidious and destructive to our values and our way of life and we will stop at nothing to defeat it.
Today's attack falls at a difficult time in the life of this city, following on from the attack on London Bridge two weeks ago – and of course the unimaginable tragedy of Grenfell Tower last week, on which I will chair another meeting of Ministers and officials later today.
But what we have seen throughout – whether in the heroism of the ordinary citizens who fought off the attackers at London Bridge; the unbreakable resolve of the residents in Kensington; or this morning the spirit of the community that apprehended this attacker – is that this is an extraordinary city of extraordinary people.
It is home to a multitude of communities that together make London one of the greatest cities on earth.
Diverse, welcoming, vibrant, compassionate, confident and determined never to give in to hate.
These are the values that define this city. These are the values that define this country. These are the values that this government will uphold. These are the values that will prevail.
The BBC has obtained footage of the suspected attacker being pinned to the ground by members of the Muslim community shortly after the suspected terror attack.
One person can be heard shouting, "Why do you kill Muslims?" as others try to restrain him.
More video has emerged of the suspected attacker being detained by police in the aftermath of the incident.
The man, aged 48, was arrested on suspicion of attempted murder.
Prime Minister Theresa May has been speaking outside Number 10.
She described the suspected terror attack as "every bit as sickening" as the other recent terrorist attacks.
She says her government is determined to stamp out extremism of all forms.
Extremist monitoring group Site says white supremacists have celebrated the attack.
One declared it as "hope for the British".
IBTimes UK reporter Isabelle Gerretsen has reported on what witnesses saw during the attack.
The terror suspect shouted "kill me" as he was pinned down by bystanders, onlookers said.
You can read our full story here:
The Independent is reporting that the suspected attacker "tried to flee on foot but ran down a dead-end street, forcing him to run back towards [the] crowd of people he had just attacked".
The Secretary of State for Wales, Alun Cairns MP, said South Wales Police was working with officers from London on the investigation.
The van used in the suspected terror attack had the logo of Pontyclun Van Hire on the front and side. The company is based near Cardiff.
Cairns MP said: "I have this morning spoken to the Chief Constable of South Wales Police, Mr Peter Vaughan.
"He has assured me that his team is fully engaged and working in partnership with the London Metropolitan Police as the investigation into the abhorrent attack at Finsbury Park gets under way.
"I am working closely with colleagues across Whitehall and receiving regular updates. It is crucial that the authorities are now given the time and the space to conduct these important enquiries.
"My thoughts and prayers are with all those affected today."

Earlier today the Archbishop of Canterbury, Justin Welby, condemned the attack, and warned: "Violence only begets more violence."
Buzzfeed reporter James Ball, who lives a short distance from the scene of the suspected terror attack, tweets:
Commenting on the terrorist incident near Finsbury Park mosque in north London, Liberal Democrat leader Tim Farron said:
"The Finsbury Park attack is senseless barbarism. Yet again we are rocked by a horrific incident for which there is no rhyme or reason.
"People who commit these heinous acts want to divide us, force us to turn in on ourselves and fight each other. We cannot and must not let them win. Our values matter, we must stand together.
"My deepest sympathies are with the victims and their families.
"I would like to pay tribute to the bravery and dedication of the emergency services, who, yet again, have gone above and beyond to help those in need. In these moments while others run in the opposite direction, our emergency services run towards danger."
Secretary of State for Communities and Local Government, Sajid Javid, has arrived in Finsbury Park to meet residents and emergency service workers. He is also speaking with the media.
Miqdaad Versi, assistant secretary general of the Muslim Council of Britain, has welcomed news of extra police and patrols around mosques in the wake of the attack.
But he said not enough had been done in the past to prevent attacks on Muslims.
He told the BBC: "Many of people across the country [have] been talking about a rise in hate crime against Muslims for a long time. This is not a one-time incident. It's happened again and again and again. There's been a bomb against Finsbury Park Mosque, which happened last year. There's been a murder of a Muslim individual, a terror attack a couple of years ago. There's been attack after attack against Muslims and it feels that this is not being taken seriously. Muslim communities are worried."
Local MP and Labour leader Jeremy Corbyn has been speaking to Sky News at the scene.
"I live down there on Seven Sisters Road, and obviously I was aware of the incident very quickly. There was a number of police vehicles and a helicopter overhead. I know the people in Muslim Welfare House and the mosque extremely well, and the community very well.
"I came here last night to talk to the police and the firefighters and ambulance who were here. I have to say the response by all three emergency services was very timely and very quick.
"The police managed to arrest the suspect who was driving the van and take him away from the area. And sadly the gentleman who died [his] body was on the ground and was covered respectfully by a tent so that forensic examination could take place."
