I don't actually live in London, about 40 minutes away. Both my father and sister work in London however. There was a real rush this morning to try and get through to them, but mobile phone networks had been closed down to try and prevent remote detonations.
In the end my dad was in his office, and I got through to my sister's office who had been in contact with her. She was in the underground when it got evacuated, and then on a bus which got evacuated too.
All is fine though.
