Riots have broken out in London for a third consecutive day, this time in broad daylight. Central Hackney, in the east, was cordoned off as youths armed with baseball bats smashed shop windows and hurled missiles at police officers. In the southeast, a fire in a shop in Peckham spread to nearby flats; vehicles were also set ablaze. Naomi Grimley has more.
Any hopes that the rioting in London was going to die down are fading by the hour. Unrest has broken out in Hackney, in the east of the city, as well as Lewisham and Peckham, in the south. Police are also confirming that the UK's second city of Birmingham is being targeted with youths smashing shopping centre windows there.

The Acting Commissioner for the Metropolitan Police, Tim Godwin, said he wanted the public to help put an end to the rioting.
"I do urge now that parents start contacting their children and asking where their children are. There are far too many spectators who are getting in the way of the police operations to tackle criminal thuggery and burglary. And I'm imploring that people within those communities actually start clearing the streets to enable my police officers to deal with the criminality that is occurring in front of them."
