London authorities have arrested seven people in relation to the Westminster attacks on Wednesday.
The Metropolitan Police had searched six addresses and made seven arrests.
Defense Secretary Michael Fallon repeated what was earlier announced- that the authorities are looking at the attack as linked to Islamic terrorism.
Fallon also said that police authorities are working non-stop to investigate the attacks further. He said the police are particularly looking closer at the attacker's background. Police are also finding out how the attacker got hold of the car he used for the attacks, and where the car was the past two days.
The police are also investigating who may have helped the attacker, and the others he may have contacted to carry out his attacks.
Fallon and the police authorities refuse to name the attacker at this point, although they have already found out his identity.
The police also corrected their initial announcement- saying four people, and not five died in the attacks. They also updated that 29 people hurt in the attacks were treated in the hospital, with seven people in critical condition. Earlier, it was reported by the police that three people were in critical condition.
The black-clad attacker drove his car through the crowd of people that included schoolchildren on Westminster Bridge. He was armed with two knives.
MPs were returning to the Parliament to prove that lives in London will not be disrupted because of the attacks. Prime Minister Theresa May also announced that aside from the Parliament meeting as normal, everyone must come together as normal.
May said people from London and all visitors around the world should get up and go about their day as usual.
May urged the people to "live their lives." She said that everyone will all move forward together, never giving in to terror and never allowing the voices of hate and evil to drive people apart.
