Unrest spreads across London, to other English cities
Rioting has spread across London on a third night of violence, with unrest flaring up in other English cities.
An extra 1,700 police officers were deployed in London, BBC News said.
Birmingham, Liverpool, Manchester, Nottingham and Bristol saw violence.
The prime minister has returned early from his holiday to discuss the unrest, which first flared on Saturday after a peaceful protest in Tottenham over the fatal shooting of a man by police.
At least 334 people have been arrested and 69 charged following the riots across London over the past three days, according to Scotland Yard.
