Update

Heard from my friend in London, thankfully she is safe.
She had a small report and promised some more details:

i am ok, and so are my other people here. work was chaos though--we were
in accident and emergency all day, dealing with major burns and blast trauma,
and there were swarms of press everywhere. we have been waiting for
this.

Echoing the common theme from most Britons that it wasn't 'if' but 'when'. Will update more as I recieve.
