Deja Vu in London - sorta

3 explosions in subway stations, one on a bus. Sound familiar?

These explosions were tiny. Only one person has been reported as injured. The damage to the bus is minimal (the bus company says windows were blown out, police say they saw no damage).

Sounds to me like a hastily thrown together copy-cat attempt. I think the question will be, was this just a stupid prank that someone thought was funny, or was it done with actual terror motivations?

The news reports seem to be leaning towars less capable terrorists using sub-par explosives that were not mixed properly or sat on the shelf for too long. I guess they would get a failing grade in Snapes potion class.
