Update:
7 blasts, across Tube and buses. Mobile phone not working as they are been restricted to to emergency services; also some news that mobiles may have been used as a trigger. Very few trains coming into the city, reports that road traffic restricteds. All the blinds now closed on the building to protect from bomb blasts; the Prime Minister states that it was definitely terrrorists (although that’s a blindingly obvious statement giving the pictures we’re seeing).
One weird thing is looking down onto Oxford street and seeing no buses at all, and very little other traffic. Normallly its chockablock with buses, all nose to tail.
We’ve been advised to stay in the building.
