As Carlotta Gall's report in the New York Times details, the bombing of a village in Damadola, Pakistan, was ostensibly targeting Al Qaeda number two man Ayman al-Zawahiri. Instead the strike resulted in at least 18 civilian deaths, including six children.
But the report continues:
[A] Pakistani official who spoke of Mr. Zawahiri suggested that the death toll was higher, and he said that at least 11 militants had been killed in the attack. Seven of the dead were Arab fighters, and another four were Pakistani militants from Punjab Province, said the official, who spoke on condition of anonymity because he was not authorized to brief the news media.
News that America is doing what it does best - bombing targets indiscriminately and with information so shady it makes Don Quixote look reliable - is not surprising in itself. News that they're doing so in densely populated regions of countries they're supposedly on good terms with though, is something else entirely.
