LONDON, June 19 (Reuters) - A van plowed into worshippers near a London mosque in the early hours of Monday, injuring 10 people, two of them seriously, in what Prime Minister Theresa May said was a "sickening" terrorist attack on Muslims.
The vehicle swerved into a group of mainly North and West African people shortly after midnight as they left prayers at the Muslim Welfare House and the nearby Finsbury Park Mosque in north London, one of the biggest in Britain.
The driver, a 47-year-old white man, was grabbed at the scene by locals and pinned down until police arrived.
The man was not named by police but local media reported he was a father of four who lived in Wales. He was held on suspicion of attempted murder which was later extended to preparing or instigating terrorism, including murder and attempted murder.
After being seized, he said he had wanted to kill "many Muslim people," one witness told journalists.
A man, who had earlier suffered a heart attack, died at the scene but it was not clear if his death was connected to the van attack.[ad number=“1”]
"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," May told reporters outside her Downing Street office.
"This was an attack on Muslims near their place of worship," said May who later visited the mosque.
The White House said U.S. President Donald Trump was receiving regular updates on the attack. "We've made it very clear to our British allies that we stand ready to provide any support and assistance that they may need," White House spokesman Sean Spicer told reporters at a briefing.
The attack was the fourth since March in Britain and the third to involve a vehicle deliberately driven at pedestrians.
It came at a tumultuous time for the government with Britain starting complex divorce talks with the European Union and May negotiating with a small Northern Irish party to stay in power after losing her parliamentary majority in a snap election that backfired.[ad number=“2”]
The mosques' worshippers had just left special prayers during the Muslim holy month of Ramadan.
Usain Ali, 28, said he heard a bang and ran for his life.
"When I looked back, I thought it was a car accident, but people were shouting, screaming and I realized this was a man choosing to terrorize people who are praying," he told Reuters. "He chose exactly the time that people pray, and the mosque is too small and full, so some pray outside."
Another witness Yann Bouhllissa, 38, said he had been tending an old man who had suffered a heart attack when the van was driven at them. The driver was then seized by locals.
"One guy caught the guy and brought him down," Bouhllissa told Reuters. "When he was on the floor, the guy asked 'why do you do that?'. He said 'Because I want to kill many Muslim people'."
Mohammed Mahmoud, the imam from the Muslim Welfare House, stepped in to ensure the van driver was not hurt until he was bundled into a police van.
"We found that a group of people quickly started to collect around him ... and some tried to hit him either with kicks or punches. By God's grace we managed to surround him and to protect him from any harm," Mahmoud told reporters.
"We stopped all forms of attack and abuse towards him that were coming from every angle."
Neil Basu, senior national co-ordinator for counter-terrorism policing, said restraint shown by locals was "commendable."
In addition to the man who died, 10 people were injured, with eight taken to hospital, two in a very serious condition, police said.
Security Minister Ben Wallace said the man was "not known to the authorities in the space of extremism or far-right extremism."
Police, who believe he was acting alone, were searching addresses in Cardiff, Wales, where the vehicle hire company that the van was rented from is based.[ad number=“3”]
Attacks in London, Manchester
The latest incident took place just over two weeks after three Islamist militants drove into pedestrians on London Bridge and stabbed people at nearby restaurants and bars, killing eight..
A suicide bombing at a pop concert in Manchester, northern England, in May also killed 22 people, while in March, a man drove a rented car into pedestrians on Westminster Bridge in London and stabbed a policeman to death before being shot dead. Five people were killed in that attack.
Five other terrorism plots have been foiled since March, police say.
May, weakened after losing her parliamentary majority in a June 8 election she had called to strengthen her hand in Brexit talks, has faced criticism for her record on security after the previous series of attacks blamed on Islamist militants.
London Mayor Sadiq Khan has called on her to reverse planned police spending cuts. She has also been criticized for her response to a fire in a London tower block last Wednesday which killed at least 79 people.
"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," May said.
She promised action to stamp out all forms of hatred, saying there had been far too much tolerance of extremism in Britain over many years.
Police have said hate crimes rose after the London Bridge attack and more officers would be deployed to provide reassurance to mosques.
The Muslim Council of Britain said Monday's attack on mosque worshippers was the most violent manifestation of Islamophobia in Britain in recent months and called for extra security at places of worship.
Finsbury Park Mosque said it was a "callous terrorist attack" and noted it had occurred almost exactly a year after a man obsessed with Nazis and extreme right-wing ideology murdered lawmaker Jo Cox, a former humanitarian aid worker.
The mosque itself gained notoriety more than a decade ago for sermons by radical cleric Abu Hamza al-Masri, who was sentenced to life in a U.S. prison in January 2015 after being convicted of terrorism-related charges.
However, a new board of trustees and management took over in February 2005, a year after Abu Hamza was arrested by British police. Attendance has greatly increased since then among worshippers from various communities, according to the mosque's website.
