British Prime Minister Theresa May while addressing the nation on Saturday condemned the London attacks in which seven people were killed and sent her condolences to the families of victims.
She also thanked police and emergency services for their swift response.
The Prime Minister also said Thursday’s general election will take place as planned.
She claimed there was “too much tolerance” of Islamist extremism in the UK as she vowed a clampdown in the wake of the third terror attack to hit the UK this year.
The attack has left seven people dead and 48 others injured after three masked men drove a van into pedestrians on London Bridge before leaping out and launching a stabbing spree in nearby bars and restaurants.
Police said the three attackers, wearing fake suicide belts to sow further panic, were shot dead within eight minutes of police receiving the first emergency call just after 10 p.m. local time. Authorities announced 12 arrests on Sunday.
