Al Qaeda ‘train attack’ plans revealed

Despite the intense violence during the operation, the US special forces were able to remove DVDs, computers and papers from the compound in Abbottobad where bin Laden is thought to have hidden for up to six years.

Details are still emerging but photos indicate a short bloody struggle that had been long in the planning.

The revelation of a possible planned attack on the rail sector has prompted an intensification of security especially in New York where hundreds of thousands of commuters use the trains to get to work.

The credibility of a plot is being taken very seriously, underlined by the fact that any attack would coincide with the tenth anniversary of 9/11 later this year.
