Palestine Press Agency - which is very anti-Hamas - publishes a scoop that cement is getting into Gaza via the Rafah crossing.
This seems to be the cement that Qatar had promised Hamas over a year ago, which had started entering Gaza via Rafah.
The article implies that the projects that Hamas is using the cement for are not necessarily the ones that Qatar earmarked it for. Qatar intended for the building materials to help build a new village and also for some infrastructure projects like repaving roads. Hamas seems to be using it for its own purposed (kidnappng tunnels, anyone?)
Hamas also appears to be selling the cement in order to gain some much needed cash.
Incidentally, the ability for Egypt to send any commercial materials through Rafah is in itself enough to prove that Gaza is not "occupied" by Israel, since Israel has no control over that border.
