Explosions in Lebanon

This is obviously a very important story, that I expect Rob will have something to say about at some point. For now, this thread is for a general discussion of it and related topics.

Another wave of wireless devices exploded in Lebanon on Wednesday afternoon, local officials said, a day after at least 12 people were killed and thousands more injured in Lebanon in an apparently coordinated attack that targeted members of Hezbollah by blowing up their pagers.

At least nine people were killed and more than 300 wounded in the second wave of blasts, according to the Lebanese health ministry, even as the country reeled from a stunning day of explosions that wounded and maimed thousands as pagers detonated in hands and pockets. The attack embarrassed Hezbollah, incapacitated many of its members, and ratcheted up fears of a wider escalation between the Iran-backed Lebanese armed group and Israel.
