This is Israeli occupation

"Amid the endless, horrifying statistics a few stand out: of Gaza's 640 schools, 18 were completely destroyed and 280 damaged in Israeli attacks. Two-hundred-and-fifty students and 15 teachers were killed. Of 122 health facilities assessed by the World Health Organization, 48 percent were damaged or destroyed. Ninety percent of households in Gaza still experience power cuts for four to eight hours per day due to Israeli attacks on the power grid and degradation caused by the blockade. Forty-six percent of Gaza's once productive agricultural land is out of use due to Israeli damage to farms and Israeli-declared free fire zones. Gaza's exports of more than 130,000 tons per year of tomatoes, flowers, strawberries and other fruit have fallen to zero.
That "much of Gaza still lies in ruins," a coalition of international aid agencies stated recently, "is not an accident; it is a matter of policy." This policy has been clear all along and it has nothing to do with Israeli "security.""
