Five homes in Leeds are being subjected to detailed forensic examination as there is apparently evidence to link them directly with the bombings in London last week.
As I write this it has just been announced on the 1pm news on BBC1 that a 'controlled explosion' has been made at one of the Leeds addresses (Burley Roard, if I got that right?) - no further details of this at present.
13.47 - BBC News24 is now showing aerial pictures of parts of the cordoned-off area. The controlled explosion was carried out by robot. 500 people have been evacuated from the area. One of the houses is apparently undergoing particularly close scrutiny, now that the controlled explosion has been carried out.
