On Wednesday, Gaza building suppliers refused to accept building materials being imported from Israel through the Kerem Shalom crossing.
The reason was because Hamas unilaterally added a major tax on all such materials, and they did not believe they coul dpay the taxes and still make a profit. (Cement and other materials in Gaza have a fixed price.)
The materials that the Gaza suppliers refused to accept included cement, aggregate and iron.
From the mainstream media, you wouldn't know that Israel is bringing truckloads of cement every day, that Hamas is interfering with the distribution of those materials by imposing arbitrary taxes, and that Gaza suppliers are angry at Hamas, not Israel.
