British police say they believe the attacker who killed three people including a police officer outside Parliament acted alone and was 'inspired by international terrorism.'

Metropolitan Police counterterrorism chief Mark Rowley says that police have raided six addresses and arrested seven people in connection with Wednesday's attack by a knife-wielding man who also mowed down pedestrians with an SUV. Rowley refused to identify the attacker.

He revised the death toll down to four, including the attacker, a police officer guarding Parliament and two civilians. He said that 29 people required hospitalization and seven of them are in critical condition.

Turkish President Recep Tayyip Erdogan has condemned the attack outside Britain's Parliament in London.

The rampage occurred hours after Erdogan warned that the safety of Western citizens could be in peril if European nations persist in what he described as their arrogant conduct.

In a series of tweets posted late Wednesday, Erdogan said Turkey shared "the pain of the United Kingdom."

Erdogan tweeted: "We stand in solidarity with the U.K., our friend and ally, against terrorism, the greatest threat to global peace and security."

Earlier Wednesday, Erdogan warned that Europeans wouldn't be able to walk the streets safely, in remarks he made amid tensions over Dutch and German restrictions on Turkish ministers wanting to hold campaign meetings with Turkish citizens.

British armed police have carried out a raid on a property in the central city of Birmingham, after an attacker killed four people before being fatally shot by police within Parliament's grounds.

Police refused to say if the raid was linked to the rampage in the heart of Britain's seat of power. But British media including the Press Association on Thursday quoted an unnamed witness saying that the operation was linked to the attack that also injured around 40 people.

A knife-wielding man 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. He hasn't been identified. Three pedestrians were among the dead.
