No additional security measures in Mumbai, Delhi after Westminster attack

New Delhi: There will be no major escalation in security measures in the metropolitan cities of India - Delhi, Mumbai, Bengaluru and Chennai - following the major terror attack outside the Houses of Parliament in London on Wednesday.

Earlier on Wednesday, the lockdown in the Westminster attack came to an end after several hours.

Five people, including a police officer, died and at least 40 people were injured in the attack.

Assistant Deputy Commissioner Mark Rowley named the police officer that has died as Keith Palmer.

Palmer, who was stabbed by a lone attacker attempting to enter the House of Commons, had succumbed to his injury. The suspect was also shot and killed, as reported by The Guardian.

Rowley confirmed that, besides Palmer, three members of the public were also killed.

He, however, declined to give any details of the attacker, but said he was thought to be inspired by international terrorism.

U.K. Prime Minister Theresa May described the attack as "sick and depraved."

May praised the "exceptional bravery of the police and the security services, who ran towards the danger as they encouraged others to move away." She also paid tribute to Palmer.

The U.K. Parliament confirmed it would be open as usual on Thursday.

Sushma Swaraj, Minister of External Affairs, India, showed solidarity with London and assured that there was no Indian casualty reported.
