Dr Ather Hussain says Islam does not condone people driving cars into others or using suicide vests.

Police have seized a van and two cars in Birmingham after an armed raid on a three-storey house.

The property is in Winson Green, where a man was reportedly arrested by police early on Thursday.

A white Ford Ka, a silver BMW estate car, and a red Renault Kangoo were taken away by recovery trucks this afternoon.

Mr Mackey told the officers "we stand shoulder-to-shoulder, whatever our fears or the threat, knowing our fellow officers will always be there for us".

“As police officers, we have a special bond with the public, as protectors and guardians. It is a bond that grows stronger in adversity."  

New police officers are being sworn in at a ceremony in Hendon, north-west London. 

In Acting Commissioner Craig Mackey's address, he honoured "fallen hero" PC Keith Palmer. 

A few moments later the recruits held a minute's silence for him.

Charlie Winter, senior research fellow at the International Centre for the Study of Radicalisation and Political Violence, tells the BBC "the age that we live in is one of unsophisticated tactics but high-impact terrorism." 

He says the Westminster attack is "much more difficult to defend against" but is a "microcosm of what the terrorist threat that we face in the UK is today."  

Jaharn Mahmood, who works with young Muslim men in Birmingham on anti-radicalisation projects and used to advise the government on counter-terrorism, tells the BBC the community didn't know Khalid Masood and believes he was acting alone.

"The landlord of where he was staying is someone I know personally. I spoke to him yesterday and he says he had never met him," Mr Mahmood says. 

"But the location is very interesting. Hagley Road is out of any Muslim community; it's not part of a community and it seems like this guy was isolated and he was working as a lone act. I have put word out asking for someone who knows this guy and normally I get some feedback, but this guy we have absolutely nothing on him. He's like a ghost."

The Prince of Wales is visiting victims in hospital. 

Prince Charles has arrived at King's College Hospital, where he will also meet paramedics and support staff involved in looking after patients. 

The hospital treated eight people initially, two of whom have since been discharged, and of the remaining six, one has died - 75-year-old Leslie Rhodes, from south London. 

A Romanian man whose girlfriend was knocked into the River Thames during Wednesday's attack was due to propose to her that day, it has been revealed.

Andrei Burnaz and Andreea Cristea were holidaying in the city, Romanian Ambassador Dan Mihalache said.

It's thought the car mounted the pavement on Westminster Bridge, hitting Mr Burnaz first and then pushing Ms Cristea over the barrier and into the water. She was then rescued by a fire crew.

She has not regained consciousness but is now stable, Mr Michalache said. She has had an operation for a blood clot on her brain. Her lungs are also starting to clear.

Prime Minister Theresa May has received a number of calls from leaders around the world following Wednesday's attack.

Those offering condolences have included King Salman of Saudi Arabia, Irish Prime Minister Enda Kenny, Scottish First Minister Nicola Sturgeon, Japanese PM Shinzo Abe, South Korea's acting president Hwang Kyo-ahn and Australia's prime minister Malcolm Turnbull. 

One of his teammates pictured in the school photo with Khalid Masood says he was an extremely popular pupil, who was bright and sporty.

Kenton Till told the Daily Telegraph: "We were quite close for a few years. The picture was taken when we were taking part in a 24-hour five-a-side tournament for charity.

"Adrian was a bloody good footballer, one of the best players in the school. He was one of those kids who was very popular. He had a big personality and everyone liked him.

"He was very bright and very good at chemistry. I think he wanted to do something like that after he left school. We lost touch eventually. I remember he came to a New Year's party at my house but he was with a group of lads who were drunk and on something and my parents asked them to leave. After that we sort of lost touch.

"This has come as a huge shock to me, it is hard to take in that this is the same bloke."

More details about attacker Khalid Masood have begun to emerge.

The 52-year-old is believed to be a father-of-three.

The Metropolitan Police says he was born as Adrian Russell Ajao - but the story appears to be more confusing still, because of a string of alternative names or aliases he used.

He was entered onto the birth registry in the Dartford district of Kent as Adrian Russell Elms in the weeks after he was born on Christmas Day 1964.

Elms was his mother's maiden name, but two years after he was born she married a man with the name Ajao.

The future killer used the surnames interchangeably before he converted to Islam and became Masood.

His mother and her husband lived for a long time in Tunbridge Wells, Kent, before moving to Wales.

Their Carmarthenshire home has been searched by detectives from the Wales Extremism and Counter Terrorism Unit. Neither of them have been treated as suspects.

Will said: "We didn’t want to come across as being disrespectful to PC Palmer and other victims of Wednesday’s incident. We just wanted to show, in the two minutes that we spoke with him, how approachable, fun, but still very professional, he was."

Tyler added: "Thank you to everyone who has supported the image and we hope its use can help support the fundraising efforts for all of the victims’ families." 

A fund-raising page, external has been set up for another victim of the attack with a £200,000 target.

A British national of Spanish origin, Aysha Frade was killed  as she walked across Westminster Bridge on her way to pick up her two young daughters from school.

Officials have been asking what, if anything, could have been done differently to prevent Wednesday's attack.

Acting Deputy Commissioner Mark Rowley announced this morning a review is under way into Parliamentary security .

Some MPs have said the Carriage Gates entrance, which is used by government cars to drop off and pick up ministers, is a weak point in the perimeter.  

One security expert, Professor Anthony Glees, added that he was "very disturbed" by what he called a "complacent attitude".

But the Met Police say security arrangements were designed to be "proportionate but not overly intrusive".

A picture of attacker Khalid Masood has emerged from his school days at Huntley School for Boys in Tunbridge Wells, Kent.

The picture is believed to have been taken around 1980, when Masood, who was known as Adrian Ajao, was around 15-years-old.

A fund-raising appeal from the Metropolitan Police Federation in memory of PC Keith Palmer has reached £500,000. The money will go to his family.

The JustGivingpage, external  was set up by Stephen Redgewell, deputy general secretary of the federation, which represents rank and file officers.

Around 25,000 people have pledged support. One, Ken Smith, said simply: “Thanks Keith, I wish I had known you.”

On the night before the Westminster attack, Khalid Masood stayed at the Preston Park Hotel in Brighton.

The manager there said Masood, also known under a number of other aliases, was "joking and smiling" and "checked out peacefully".

Saveur Toumi said he had made no attempt to conceal his identity or address when checking in.

Sadiq Khan has been to meet the people who were involved in dealing with events on Wednesday.
