The strange thing, from what has been published so far, is that the explosions were all low power. It is almost as if whoever was behind it wanted to make a statement - panic, but no (or not as much) death. That makes it seem like either someone made a mistake in manufacturing the bombs, or a different group was involved acting as a copycat.
From one report, it sounds like at least one of the bomb carriers was surprised to have survived, and expected more...
Sick, no matter how you look at it.
