10:10 PM PT -- Cops say one person has died and at least 8 were injured in the attack. One person has been arrested.
A number of people have been seriously injured after a van plowed into groups of pedestrians near a notorious Muslim mosque.
The incident occurred just after midnight. London police say there are a number of casualties.
The Muslim Council of Britain says the van ran over a number of worshipers as they left the mosque.
The mosque has had a history of attracting Islamist militants, including the "shoebomber" Richard Reid and 9/11 terrorist Zacarias Moussaoui.
One person has been arrested but police are not saying if they believe more than one individual was part of the attack.
