ISIS claims role in British Parliament attack; 8 held

That brings the total number of people in custody for the Wednesday attack to nine.

The death toll from Wednesday's attack on the heart of Britain's democracy grew to five as police said one of the injured, a 75-year-man, had died in hospital after his life support was withdrawn.

Masood drove into pedestrians who were on the Westminster Bridge, killing at least two victims and injuring dozens of others, before fatally stabbing Police Constable Keith Palmer, 48.

The attack left four people dead and injured at least 50 more, 31 of whom needed hospital treatment, Rowley said.

Police believe Masood acted alone, but London's top counterterror officer Mark Rowley said police are investigating whether he "acted totally alone inspired by terrorist propaganda, or if others have encouraged, supported or directed him".

Rowley said police were "looking at his history" and appealed for any public information about him, adding: "Our investigation focuses on understanding his motivation, preparation and associates".

Although some of those he was involved with included people suspected of being keen to travel to join jihadi groups overseas, Masood "himself never did so", said a United States government source, who spoke to Reuters on condition of anonymity.

Two police officers injured in the attack are also in hospital with "significant injuries".

Searches have been either completed or are in-process at 21 locations, Rowley said.

Masood, a father of three, claimed he was an English teacher.

"Today, we meet as normal - as generations have done before us, and as future generations will continue to do", she said to lawmakers' cheers in the House of Commons.

Arrests were made in London and Birmingham, while homes were also searched in Brighton and Carmarthenshire, in west Wales.

The attack, which is being investigated as a terrorist incident, on Wednesday is Britain's deadliest since the July 7, 2005, terrorist bombings in central London that killed 52 people and injured almost 800. The Metropolitan Police said the incident was a terrorist attack.

A 32-year-old woman arrested in Manchester was bailed pending further enquiries until a date in late March. "The attack in London this week has again demonstrated the importance of worldwide efforts to confront and eradicate terrorism", the Saudi Arabian embassy said. His first conviction was in November 1983 for criminal damage.

Police on Thursday identified the man responsible for a terror attack outside Britain's Parliament as 52-year-old Khalid Masood. More candlelit vigils for the victims were scheduled on Friday in Birmingham and London.

But he was known to police and MI5 and had convictions for assaults, including Grievous Bodily Harm, possession of offensive weapons and public order offences.

"Those evil and twisted individuals who tried to destroy our shared way of life will never succeed and we condemn them", Mayor Sadiq Khan said in an address to the crowd.
