Angry Arabs Say Baghdad Market

Angry Arabs Say Baghdad Market Blast U.S. Massacre
I tend to think that these blasts are the work of Saddam Hussein, or someone like Al Quaida, seeking to inflame Iraqi and Arab opinion against the US, rather than US bombs going astray.

How many bombs fell in Baghdad before these two incidents? How many caused damage beyond their targets and the immediate vicinity? Why is it that now, when more of our bombs are going into the south, rather than Baghdad, bombs start missing wildly, and hitting the worst possible locations?
