London fortifies bridges to protect pedestrians

Concrete and metal barriers are being erected along the sidewalks on some of London’s bridges after terrorists used cars and vans to target pedestrians for the second time in just over two months.
London police on Sunday evening said commuters could expect to see more officers on the streets and more physical measures on bridges, after at least three men killed seven people at London Bridge on Saturday. That followed a similar attack in March on Westminster Bridge, near the Houses of Parliament. A police spokesman declined to say how many locations are being fortified, but at least three of the dozens in the capital are already visibly altered.
Commuters saw uniformed police officers at Tube stations around London, an unusual sight for a city where officers are less visible on the streets than in other major global cities.
“Our security and policing plans for events are being reviewed, the public will also see increased physical measures on London’s bridges to keep the public safe,” said Mark Rowley, an assistant commissioner at the Metropolitan Police Service.
