London was hit with four more bombs today, but the small explosions just appear to have been detonators. As a result, the the casualty figures so far include one person injured, with no deaths.

Speculation is that this was a copycat bombing, run by a more group that didn’t know how to design the bombs. One of the bombs, and least, appears to have been a nail bomb, so it is likely they were intended to cause more death and destruction.

What seems really odd is that the bombs went off in three subway stations and a bus, exactly like the last bombs. Why is that, when the bus bomb from last time likely was actually aimed at a subway station as well?
