For a UN Sec Gen to claim, within hours of the incident, that this disaster is "apparently deliberate" --- is beyond irresponsible; it's demented.
Suddenly I remember that the IDF had been telling EVERYONE to get out of S. Lebanon if they wanted to avoid attack. Could it be that the Israelis told the UN to get out, they said screw you, you won't shoot me, and the Israelis went ahead and reduced the target? Then Annan says well they did it on purpose, neglecting to mention that they were warned to get out. It's plausible.
