Here's what you need to know.

Three people were killed in London on Wednesday after an attacker mowed down pedestrians on Westminster Bridge and hacked at police with knives in the grounds of the Houses of Parliament.

Speaking in the House of Commons, May said the as yet unnamed man, who was shot dead by armed police inside the Palace of Westminster, had been known to MI5, the domestic security service, but had been a "peripheral figure".

May also shared more details about the attack and those it harmed, saying it injured around 40 people.

Born on Christmas Day 1964 in Kent in southeast England, Masood had been living in the West Midlands where armed police have staged several raids since the attack, storming properties in the city of Birmingham.

He had previous convictions for assaults, GBH, possession of offensive weapons and public order offences. His first conviction in 1983 was for criminal damage.

Kent-born Masood, who was shot dead in the attack, was not the subject of any current police investigations, but had a range of previous convictions.

British Prime Minister Theresa May earlier told lawmakers that Masood was "not part of the current intelligence picture".

A USA government source told Reuters that Masood had been associated with others who had expressed an interest in traveling overseas to join extremist groups.

Although police said they were confident that Masood was the sole attacker on Wednesday, counter-terrorism detectives are investigating whether he was part of a wider conspiracy. However, ISIS has provided no evidence for any direct links to the assailant, whom it did not name. But The Guardian says officers are "working on the assumption there was only one attacker".

"I heard what I thought was just a collision and then I looked through the window of the taxi and I saw someone down and then I saw a second person down and then I started filming and I saw three more people down", he said.

Police officers work in Westminster the morning after an attack in London, Britain, March 23, 2017. In addition to 12 Britons, there are four South Koreans, three French children, two Romanians, two Greeks, along with nationals of the U.S., Germany, Poland, Ireland, China, Italy and other nations.

British media described Masood as a Muslim convert, with one source telling Sky News he was a "very religious, well spoken man".

"My thoughts, prayers, and deepest sympathy are with all those who have been affected by yesterday's terrible violence".

Paramedics attempted to save him but he died.

Police said he had been "known by a number of aliases".

Factory worker Iwona Romek, 45, said Masood was her next-door neighbor in Birmingham before moving with his family a few months ago.

In the northwestern Spanish town of Betanzos, where Frade's mother was born and her two sisters run an English-language school, the mayor said: "The whole town is shocked".
