The number of the victims of attack in London increased after a 75-year-old man died in the hospital. The man, whose name was unknown, became the fourth victim of the London attack after having his life support turned off, BBC reported.

The attack occurred on Wednesday in one of the city's most popular places. Five people have died and at least 40, including police officers were injured after an attacker drove a car along a pavement in Westminster, stabbed a policeman and was shot dead by police in the grounds of Parliament. The police detained eight people in connection with yesterday's terror attack in Westminter during the raid. The attacker was 52-year-old Briton, Khalid Masood.
