The BMA's website says: "A multi-faith act of remembrance will be held in the BMA courtyard at 12 noon on Thursday 21 July, lasting about half an hour. BMA staff and members who were affected or who will be near BMA House on that day may wish to attend. For those who cannot attend, an edited film of the event will be placed later on the website."
Doctors and staff from the BMA found their headquarters turned into a mini hospital on the day of the blasts. I'm sure many lives were saved because of their work.
