London, Aug 9 (IANS): Rioters will "feel the full force of the law", warned Prime Minister David Cameron Wednesday after he cut short his holiday following three days of rioting in London.

The prime minister said the parliament was being recalled Thursday due to the violence that has spread to other cities in Britain.

The government's emergency committee Cobra has met over the deadly riots, reported BBC.

Besides London, the riots have spread to cities like Birmingham, where the England and Indian cricket teams were holed up in a hotel ahead of their Test match scheduled to begin Wednesday, Liverpool, Nottingham, Bristol and Manchester.

"We will do everything necessary to restore order to Britain's streets and make them safe for the law-abiding," said Cameron.

The prime minister said that at least 450 people have been arrested so far.

He warned rioters, "you will feel the full force of the law", and added that people should "stand together in condemnation of these crimes".

Rioters have paralysed London for the past three days.

London witnessed a third night of violence as the unrest spread to other cities. Protesters were seen destroying and looting shops, setting cars and buildings alight, and engaging in clashes with police.

Violence began in the British capital's northern district of Tottenham Saturday over the fatal shooting of a cabbie by police.

Some 300 people gathered outside a police station in Tottenham Saturday night to demand "justice" after 29-year-old cab driver and alleged drug dealer Mark Duggan was killed in Thursday's shootout with police.
