Gazans stealing sand led to sewage tragedy

From The Age:

However, construction of a new plant did not appear to have been affected by year-old international sanctions on the Palestinian Authority. The Gaza City mayor blamed the collapse on local people digging dirt from an earthen embankment around the structure and selling it to building contractors.

One can imagine that they were not selling shovelfuls of stolen dirt to these contractors. Almost certainly, since it is easier to get dirt that is above ground than to dig it, one can imagine trucks backing up to the embankment shoving in the dirt.

This is so negligent, these victims should almost be added to my list of PalArab self-deaths.
