Palestine Press Agency quotes Palestinian Contractors Union chairman Osama Kahil as saying that much of the cement smuggled into Gaza through Rafah is unsafe for building.
Kahil says there is a big risk of building without testing of the quality of cement, confirming that the Hamas government does not perform tests on building materials smuggled from the tunnels.
He claimed that the lab tests confirmed that the smuggled concrete is only half the strength of that necessary to build safe structures.
