The van continued on to Borough Market, an area of the capital known for its nightlife, where police say the suspects exited the vehicle and stabbed pedestrians.
There were also reports of a third stabbing, in the Vauxhall area of London, but police determined it was not connected to the terror incidents at London Bridge and Borough Market.
