Louisa, No it hasn't been evacuated(!). I can see the package (looks like a small briefcase) out of my front window. Needless to say, I'm now sitting in the back room. WOW! Just heard a bang! Yep, looks like they used one of those robot things to do a "controlled explosion". The bag has moved a few feet in the blast and a policeman is now inpsecting iot with a torch.
