"Monstrous": Israel destroys an aid convoy

Did Israel deliberately destroy an aid convoy?

Kevin Drum doesn't want to believe it:

...I can hardly bring myself to believe it was deliberate. That would be monstrous. On the other hand, Israel's ongoing efforts to starve the Gazan population have been pretty monstrous. What's more, their recent acquiescence to increasing aid shipments has been very much against their will. 

Deliberately destroying an aid convoy would certainly be a very effective way of continuing their starvation policy by the simple expedient of scaring off humanitarian organizations. 

Finally, in addition to all this, it's just very hard to believe that an operation so precisely calculated and carried out was due merely to sloppy intel or a careless fog-of-war mistake....
