The early afternoon explosions in London - three in the Underground and one on a bus --are eerily similar to the transit bombings from two weeks ago. Someone is obviously sending a message, even to mimic the North-South-East-West pattern. But this time, it was just detonators. A few broken windows, no serious injuries.
The message was clear, but to whom?
An attack at 1:30 in the afternoon isn't exactly hitting the rush hour. But it is catching the morning news shows in the United States.
