Tensions are running high after police shot and killed a man accused of being a gangster in the London borough of Tottenham on Thursday.
At first there was a small and reportedly calm protest by members of the man's family; but within hours the protest had escalated into arson, violence and mass looting. Parts of the borough in north London were left in ruins after crowds set fire to cars and buildings.
And there were more disturbances on Sunday night - eight kilometres away in Enfield, with shop windows smashed.
Later the British police condemned a wave of "copycat criminal activity" across the capital.
So after a weekend of destruction, looting and arson across London, we ask: What are the root causes of the violence, why did the riots break out so suddenly and why has it become such a vicious and destructive affair?
