Anti-terror barriers installed on three key London bridges

Large concrete barriers have been installed overnight at Waterloo, Lambeth and Westminster bridges.

Police have also been guarding the capital's main bridges in order to stave off any potential "copycat" attacks.

The increased measures to protect the public come just 24 hours after seven people were killed and 48 injured in a terror attack in London Bridge and Borough Market.

The white van used in the attack was able to reach speeds of more that 50mph before it was driven into victims on the bridge.

The three male attackers then jumped out of the vehicle and stabbed people with foot-long knives.

It has been reported that London's municipal governing body, City of London Corporation (COLC), ruled out installing anti-terror bollards in the London Bridge area just 24 hours before the attack.

After the Westminster Bridge terrorist atrocity in March, which killed five and left more than 50 injured, security barriers were installed outside Buckingham Palace and Windsor Castle.

Following Saturday's rampage, Metropolitan Police commissioner Cressida Dick has increased patrols on London's streets, including armed officers.
