The UK has threatened to kill access to social networking websites following the outbreak of, what the authorities have described as, the country's worst unrest in a generation.
Prime Minister David Cameron addressed a statement to the parliament on Thursday, warning to unleash a clampdown on the web-based social outfits, including Facebook, Twitter and Research in Motion, the producer of BlackBerry devices, AFP reported.
He said the government would consider applying the ban against the people, who are suspected of 'inciting violence online.'
The premier cautioned the websites to take more responsibility for their contents.
Unrest has rocked Britain in a scale unprecedented in 30 years following the police's killing of black male Mark Duggan in a shooting spree in the London suburb of Tottenham last Thursday.
The security forces fatally shot the 26-year-old after stopping his minicab to make an arrest as part of a preplanned operation.
Tension erupted on Saturday, when a few hundred people gathered outside a police station in Tottenham to protest the killing.
The protests have spread to major cities like Birmingham, Liverpool, and Bristol.
They came while the pressure on the Britons from economic stagnation has been compounded by deep public spending cuts and tax increases aimed at eliminating a budget deficit that has peaked at more than 10 percent of the GDP.
Scotland Yard has said at least 1,200 people have been arrested for taking part in the public show of outrage.
Cameron's threat, meanwhile, defied the White Hall's claim to being an advocate of human rights and freedom of expression.
