British Jihad and Islamic Supremacism Watch

In London today, a car bomb was defused outside of a central London nightclub at 2 AM (British Time), targeting up to 1,700 people with a combination of gasoline bombs and reportedly a trunk full of nails.

London police were contacted when witnesses saw a Mercedes being driven erratically near London West End night club Tiger Tiger, and the driver jumped out of the automobile and ran away. The car was reported to have two gasoline canisters and be full of nails. Witnesses subsequently saw gas canisters being removed from a Mercedes automobile by police at 4 AM BDT.

According to the Daily Mail, the apparent target, the Tiger Tiger nightclub in Haymarket, had up to 1,700 people inside. A Daily Mail senior anti-terrorist source said: "This was a viable device which could have caused massive damage and killed hundreds if it had worked. The consequences would have been terrible. This is the scenario that we have dreaded."

Shane Brighton, a counter-terrorism expert, told Sky News: "This is highly unlikely to be an Irish device, given the current state of politics there. Al Qaeda tend to go for symbolic timing."

UPDATE
Officials confirm plot involves "Islamic extremists" - photo of suspect - second car bomb found - linked to first car bomb - and Internet posting of threat night before bombing attempts

ABC reports: "British police have a 'crystal clear' picture of the man who drove the bomb-rigged silver Mercedes outside a London nightclub" and that he bears 'a close resemblance' to a man arrested by police in connection with another bomb plot but released for lack of evidence. Officials say the suspect had been taken into custody in connection with the case of al Qaeda operative Dhiren Barot. U.S. and British law enforcement officials tell ABC News it is increasingly clear Friday's bomb plot in London involves multliple vehicles, and is described by a senior official as a 'terror plot involving lslamic extremists.' "

A second car bomb was found during the day in London's West End. The Telegraph reports that "Sources revealed that officers examining a Mercedes found in an underground car park off Park Lane this afternoon discovered an explosive device inside. Earlier this afternoon Park Lane was sealed off and Hyde Park evacuated after bomb experts were called in to examine the car. Security alerts caused by the searches brought much of London to a standstill."

FOX News reports that British anti-terror police chief Peter Clarke stated" 'The vehicle was found to contain very similar materials to those that had been found in the first car,' he said. 'There was a considerable amount of fuel and gas canisters. As in the first vehicle, there was also a quantity of nails. This like the first device was potentially viable.' "

CBS News reports that "Hours before London explosives technicians dismantled a large car bomb in the heart of the British capital's tourist-rich theater district, a message appeared on one of the most widely used jihadist Internet forums, saying: 'Today I say: Rejoice, by Allah, London shall be bombed.' This was on the "al Hesbah" chat room by a person who goes by the name "Abu Osama al-Hazeen".

This type of car bombing plot is typical of other British Jihadist car bomb plots in the past, including both the July 2005 bomb plots, and the Dhiren Barot Jihadist group bomb plots.
--- In July 2005, a number of bombs and components, some packed with nails to cause death and maximum injury, were recovered from a car parked by the July 7 bombers at Luton station.
--- British Jihadist Dhiren Barot pleaded guilty to plotting a series of attacks, including detailed plans to explode limousines packed with gas cylinders, explosives and nails after leaving them in underground London parking garages or hotels.

Scotland Yard stated that detectives from Counter Terrorism Command were investigating the bomb plot.

Police said they had no warning of an attack. "The police did not have any advance intelligence of this which is worrying," said Paul Wilkinson, chairman of the Centre for the Study of Terrorism and Political Violence at St. Andrew's University in Scotland. "They will be concerned there might be other devices in the area or elsewhere in central London because if it is al-Qaeda one of their characteristics is to set off coordinated devices.''

This came on the second day of Gordon Brown's role as Prime Minister of the United Kingdom, who has urged Britons to remain vigilant following the discovery.

Traffic disruption is ongoing as London police investigate the incident; this includes closing nearby streets, diverting buses, and closing the Piccadilly Circus subway station.
