SHOCK VIDEO: First hand video shows London's street run red with blood after massive terror attack

Five jihadi terrorists shouting 'this is for Allah' have reportedly killed seven people and left dozens injured in a horrific rampage around two locations in central London.



The men, described as being 'of Mediterranean origin', mowed down up to 20 people with a white van hurtling across London Bridge at 50mph on Saturday night.



One person has been killed at London Bridge - and one of the casualties is reportedly a police officer. At least 20 people have been taken to six hospitals across London.



Attackers then began 'randomly stabbing' revellers with 12-inch hunting knives in the nearby Borough Market area of bars and restaurants in what authorities described as terrorist incidents. One man was reportedly stabbed five times in the chest.



Witnesses said the gang, with metal canisters strapped to their chests, smashed pub windows and cut the throats of drinkers, and a 'dark-skinned' man in a red tracksuit 'calmly' stabbed a man three times.



Armed police rushed to the scene where shots were heard and authorities urged Londoners on Twitter to 'run, hide, tell' if they were caught in the 'utter chaos'.



Two suspects were shot dead by a marksman outside the Wheatsheaf pub in Borough Market and one was gunned down and believed to be killed, as the remaining two suspects are on the run.



50 armed police entered Monument station with police dogs and bystanders were told to run. Bank and Monument tube stations have been closed. There are also unconfirmed reports of gunfire on Southwark Street.
