British police say they believe the attacker who killed three people including a police officer outside Parliament on Wednesday acted alone and was “inspired by international terrorism.”
Since the attack, police have raided six addresses since the attack, including in London and Birmingham, which have resulted in seven arrests in total.
Mark Rowley, assistant commissioner with the Metropolitan Police, said that police are not ready to publicly identify the attacker and they are continuing to investigate “his motivation, his preparation and his associates.”
The death toll, after some confusion Wednesday, was revised to four.
The raids come after the attacker drove an SUV into pedestrians on Westminster Bridge before crashing the vehicle into the gates of Parliament on Wednesday. He scaled the fences and later fatally stabbed a policeman before being gunned down by officers.
Prime Minister Theresa May condemned the “sick and depraved terrorist attack.”
The policeman has been identified as Keith Palmer, 48.

Rowley said that 29 people required hospitalization and seven are in critical condition.
Police were not to ready to publicly name the other two deceased until notification of next of kin, with at least one of the victims not from Britain. Those victims were identified as a woman in her 40s, and a man in his 50s.
BBC reported that in addition to Britain, the injured included those from France, Romania and South Korea.
While there is an increased police presence on Thursday, Rowley said there was no credible information of further threats.
Parliament is scheduled to be in session later in the morning.
