UK Parliament assailant Khalid Masood: 'A nice guy' turned extremist

The Islamic State group had claimed responsibility for the attacks on Thursday, saying one of its "soldiers" had carried it out.

Moreover, no prior intelligence related to him indicated he may commit a terror attack.

A GoFundMe campaign was also launched for thepolice officer Keith Palmer, another victim of the attack. Cochran succumbed to his injuries in the hospital.

Australian woman Patricia Neis-Beer was also injured in the attack.

In a tweet, President Donald Trump paid tribute to Cochran.

The British authorities raided six properties across the country on Thursday, detaining eight people in London and Birmingham, as they pressed ahead with a fast-moving investigation.

Britain's most senior counter-terror police officer, Mark Rowley, described the inquiry as "very large and fast-paced", and announced two "significant arrests" Friday. He did not specify how those arrested were linked to Wednesday's attack.

"It is still believed this attacker acted alone and police have no reason to believe there are imminent further attacks on the public".

"This was an attack on free people everywhere", she said.

A three-storey townhouse in the Winson Green area of Birmingham was among those searched in police raids, with neighbours saying Masood lived there for around seven months until December previous year.

Police said Masood was inspired by global terrorism, but have not revealed whether their investigation has identified a motive, or whether any of his associates, family or friends knew of his intentions to carry out the deadly attack.

May's comments both Wednesday and her remarks to Parliament on Thursday have struck a defiant tone.

"Detectives investigating the terrorist attack in Westminster on March 22 can confirm that the man died tonight March 23", a Scotland Yard spokesperson said. "We stand up for our values and we show the world we are the greatest city in the world".

The crowd at the vigil in London's Trafalgar Square for the victims of the attack at Westminster. "Masood was also known by a number of aliases", read a statement from London Metropolitan Police.

Here's what you need to know.

"When Londoners face adversity we always pull together".

The 53-year-old, who was born Adrian Elms in Kent, killed and maimed at least 40 civilians when he rampaged over Westminster Bridge in a rented 4×4 and fatally stabbed PC Palmer outside Parliament. Police officers marked the occasion, standing silently outside the headquarters of London's Metropolitan Police nearby.

UK Foreign Secretary Boris Johnson earlier led the UN Security Council in a moment of silence for the victims of terror in London and elsewhere. Two police officers injured in the attack are also in hospital with "significant injuries".

It began with an SUV being driven over Westminster Bridge right by the House of Commons.

Rowley acknowledged that Muslim communities will "feel anxious" over fears of an Islamophobic backlash, and said police would work with community leaders to ensure protection. "Other officers shot the attacker".
