A van rammed into people on London Bridge earlier tonight. Eyewitnesses reported that the van was travelling at 50mph (80kmph).
Casualty counts have not been released yet.
Transport for London said the bridge has been closed in both directions due to a "major police incident".
A man has been arrested by police.
Earlier this year, in a similar incident, a car rammed into pedestrians on the sidewalk in midtown New York.
In the last year, Europe has seen at least 3 terrorist attacks where a truck was used as the weapon.
