Westminster terror attack: 75-year-old man dies from injuries
A 75-year-old man has died from injuries he sustained during the Westminster terror attack.
The man had been receiving medical treatment in hospital but life support was withdrawn on Thursday.
Scotland Yard said the man's next of kin were informed and are now receiving support from liaison officers.
A statement from police said: 'Detectives investigating the terrorist attack in Westminster on Wednesday, 22 March can confirm that a 75-year-old man died tonight, Thursday, 23 March."
Details about the identity of the victim have not been released.
PC Keith Palmer, Aysha Frade and US tourist Kurt Cochran were killed in Wednesday's attack. Police named Khalid Masood, 52, as man they believe carried out the attack which left four dead and 40 injured.
Earlier on Thursday London Mayor Sadiq Khan told the thousands of people who responded to his personal invitation to come together in solidarity and sympathy at the Trafalgar Square vigil, that "those evil and twisted individuals who tried to destroy our shared way of life will never succeed and we condemn them".
He spoke after detectives investigating Wednesday's attacks on Westminster Bridge and at the Houses of Parliament said they had arrested three women and five men on suspicion of preparing terrorist acts.
The suspects were held in raids in London and Birmingham as neighbours of Masood, a 52-year-old with a string of criminal convictions including possession of a knife, spoke of their shock.
Scotland Yard said Masood was not the subject of any current investigations before Wednesday's outrage and there was "no prior intelligence about his intent to mount a terrorist attack".
However, he was known to police and MI5 and had convictions for assaults, including GBH, possession of offensive weapons and public order offences.
Masood was born in Kent on Christmas Day in 1964 and detectives believe he was most recently living in the West Midlands. He was also known by a number of aliases.
One former neighbour, Iwona Romek, speaking in Winson Green, Birmingham, said she could not believe her eyes when she realised the man who had lived near her was the man responsible for the attack.
She said: "Now I'm scared that someone like that was living close to me."
Three people were killed when the knife-wielding attacker ploughed a car through pedestrians on Westminster Bridge, before storming the Parliamentary estate. He was shot dead.
A day later crowds gathered in Trafalgar Square for a candlelit vigil in memory of the victims.
In praise of the bravery of the emergency services responding to the attack, Mr Khan said: "When Londoners face adversity we always pull together. We stand up for our values and we show the world we are the greatest city in the world."
Earlier Prime Minister Theresa May disclosed the terrorist was British-born and was once investigated in relation to concerns about violent extremism some years ago, but was a "peripheral figure".
Home Secretary Amber Rudd defended the security and intelligence agencies, saying: "The fact that he was known to them doesn't mean that somebody has 24-hour cover."
She disclosed Masood had spent time in jail, but said it was not for terrorist-related offences.
As police and intelligence agencies mounted a massive investigation to piece together the killer's movements in the lead-up to the attack:
:: Searches were carried out at three addresses in Birmingham and one each in east London, Brighton, south-east London and Carmarthenshire.
:: A 39-year-old woman was arrested in east London while a 21-year-old woman and a 23-year-old man were held at one address in Birmingham.
:: A 26-year-old woman and three men aged 28, 27 and 26 were arrested at another address in Birmingham.
:: They were all held overnight while a 58-year-old man was arrested on Thursday at a third address in Birmingham.
:: Investigators are working on the basis that the attacker acted alone.
:: Car firm Enterprise confirmed the Hyundai used in the attack was one of its vehicles.
:: Islamic State claimed the killer was one of its "soldiers".
:: A review of security arrangements at Westminster was launched.
The Prime Minister addressed MPs as they gathered at the usual time inside the Palace of Westminster.
In a defiant message to a packed House of Commons, Mrs May said: "We will never waver in the face of terrorism."
Paying tribute to Pc Keith Palmer, who died after being stabbed, she said: "He was every inch a hero and his actions will never be forgotten."
The officer's family described him as "brave and courageous", saying his friends and relatives are "shocked and devastated".
The identities of the terrorist's victims on Westminster Bridge have emerged, one a US tourist from Utah celebrating his wedding anniversary, the other a "highly regarded and loved" member of college staff.
Kurt Cochran and his wife, Melissa, on the last day of a trip celebrating their 25th anniversary, were visiting her parents, who are serving as Mormon missionaries in London. Mrs Cochran was badly injured.
Aysha Frade, who worked in administration at independent sixth-form school DLD College London, in Westminster, is understood to have been 43 and married with two daughters.
Meanwhile, Islamic State made its first public pronouncement since the atrocity, claiming in a statement: "The attacker yesterday in front of the British Parliament in London was a soldier of the Islamic State executing the operation in response to calls to target citizens of coalition nations."
Commentators pointed out the terror group has a record of opportunistically claiming attacks and said it was significant the statement did not appear to claim it had directed the strike.
A minute's silence was held nationwide at 9.33am, including in the Palace of Westminster and at New Scotland Yard, to commemorate the three innocent people who were killed.
Forty other people were injured in the attack, with 29 treated in hospital.
Five people remained in a critical condition on Thursday evening, two with life-threatening injuries.
The casualties included 12 Britons, three French children, two Romanians, four South Koreans, two Greeks, and one each from Germany, Poland, Ireland, China, Italy and the United States.
Three police officers were also hurt, two of them seriously.
