London Riots: Liverpool New Outbreak Of Violence

LONDON - British police say violence and looting has spread to a third city, with authorities handling outbreaks of violence in the northern city of Liverpool.

Liverpool's police department said officers were responding to a "number of isolated outbreaks of disorder," including vehicles set ablaze and buildings attacked in the city's southern neighbourhoods.

It follows a major escalation of rioting across London since a wave of violence first broke out on Saturday night. Police in the country's central city of Birmingham also confirmed more than 30 people had been arrested after shops in a main retail district were attacked.

Shops and cars were set ablaze across London late Monday and early on Tuesday as authorities struggled to contain a third night of unrest in Britain's capital, which will host next summer's Olympic Games.
