On the 11th February I wrote -
"I read that the Israelis charge something like £100 on every wagon-load of humanitarian aid passing through their checkpoints. It sounds credible, considering that they are trying to starve the people of Gaza to death, but I'd like to find some support for the claim."

Now I read -
"And while a conference with the stated aim of helping reconstruct Gaza is subverted by efforts to prop up the PA, the Israeli government, in the style of a banana republic, is shaking down aid convoys going into Gaza. Each truck of humanitarian aid is forced to pay a $1000 'handling fee' — unless of course it’s determined to be carrying 'luxury goods' such as macaroni, in which case it isn’t allowed to enter."

Worse than I was led to believe.

Addendum: more on this -
"Israel continues to block goods on trucks from entering Karni, the one border crossing point with sophisticated security screening equipment and the capacity to handle up to 750 trucks per day. Sufa crossing, which can also accommodate trucks on a smaller scale, also remains closed. Instead, Israel requires all trucks to enter through Kerem Shalom, located near Gaza's southern tip, where every item on trucks must be unloaded, inspected, repackaged and reloaded, with a "handling fee" of US$1,000 per truck."
