Watching Sky sports 2 - England 92/2 - and play interupted by an explosion on the boundary by the advertising hoardings. Pundits are saying bomb, but it seems to me like it was of large firecracker similar to a thunderflash. There is not a great deal of damage and very few members of the crowd are injured and the injuries appear to be minor. Were it a bomb, or even a grenade, the injuries should be greater. Only an hour until stumps so play will probably be abandoned.
