Scotland Yard foils what could have been a massively bloody terror rampage through London:

Eight men have been arrested today on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism. Details of the arrests are as follows - two in Uxbridge one each in Ilford, Horley and Slough and three in Crawley. They will be interviewed by officers from the Metropolitan Police Anti-Terrorist Branch. This operation is not linked to either Irish Republican terrorism or to the recent attack in Madrid. The men who have been arrested are all British citizens. They are aged between 17 and 32.

While London cops don't specify the background of the suspects, they say this:

As we have said on many occasions in the past, we in the police service know that the overwhelming majority of the Muslim community are law abiding and completely reject all forms of violence. We have a responsibility to all communities to investigate suspected terrorist activity.

This story will likely develop throughout the day. Check The Command Post for more details.
