Five people were killed and about 40 others were injured in London, yesterday close to Britain's parliament.

The incident occurred after a car mowed down pedestrians on a bridge and a suspected Islamist-inspired attacker stabbed a policeman.

The police called this incident as a “marauding terrorist attack”. The man behind the attack was shot dead by armed Scotland Yard officers.

The Metropolitan Police identified the stabbed police officer as 48-year-old Keith Palmer, who served 15 years, and also confirmed that the attacker was known to the police.

Four other victims were among those, hit by the car, as it sped across Westminster Bridge before crashing into railings just outside the parliament.

Prime Minister Theresa May condemned the terror attack as "sick and depraved"  attack on democratic values, which was doomed to failure.

The location of this attack was no accident," the Minister said in a statement.

"The terrorist chose to strike at the heart of our capital city, where people of all nationalities, religions and cultures come together to celebrate the values of liberty, democracy and freedom of speech." she added.

Britain's most senior counter-terrorism officer, Mark Rowley, told reporters, that the attack started when a car was driven over Westminster Bridge, hitting and injuring members of the public and three police officers.

"A car then crashed near to parliament and at least one man, armed with a knife, continued the attack and tried to enter parliament," Rowley said.

“The Officer said, the police's fast-paced investigation was working on the assumption that the attack was Islamist-related terrorism”.

“Police believed they knew the identity of the attacker, but would not provide details at this stage, he added.

According to Reports, “loud bangs were heard in parliament during the attack and shortly afterwards saw the knife man and the stabbed policeman lying on the ground in a courtyard within the gates of parliament.”

“Theresa May also paid tributes to the exceptional men and women of the police force who responded to the attack.

“We will all move forward together, never giving in to terror and never allowing the voices of hate and evil to drive us apart,” she said.

Earlier, Scotland Yard Officers, had called on the public to remain vigilant.

A review of policing strategy across the city was underway, with additional police officers being deployed across London, was said by the Officers.

Indian Prime Minister, Mr. Narendra Modi, expressed grief over the attack. “Deeply saddened by the terror attack in London. Our thoughts and prayers are with the victims and their families,” Modi tweeted.

Furthermore, the Indian High Commission in London has set up a special “Public Response Unit” for any Indians caught up in the terror attack.
