GAZA CITY (Ma'an) -- Israeli forces killed at least 100 Palestinians on Sunday including 66 in a single neighborhood of Gaza City, bringing the 13-day death toll to 437.
The assault on Gaza -- which has also left 18 Israels dead -- is the largest and deadliest attack on the besieged coastal enclave since 2008. More than 200 Palestinians have died since the ground invasion began on Thursday.
On Sunday, 66 bodies were recovered from the Shujaiyya neighborhood in eastern Gaza City, in what medical authorities called a "massacre" and a level of violence not seen before in the ongoing conflict.
At least 500 Palestinians were injured in Israeli attacks on Wednesday, with the total surpassing 3,000 as Gazan hospitals struggled to cope with the surge and facing shortages of medical supplies, doctors, and hospital beds.
Hospitals were also facing continuous power cuts, as electricity has fallen by more than 70 percent as a result of Israeli shelling and the siege itself, which even prior to the assault had reduced electricity availability to eight-hour stints.
60 thousand Gazans fled their homes on Sunday alone amid the mass killing in the Shujaiyya neighborhood, adding to a total number of displaced that has now hit 135,000.
Sources familiar with the situation argued, however, that there is not a single place safe from Israeli attack in the besieged coastal enclave, as shelling from land and sea as well as air strikes have not left any region untouched.
Palestinian analysts expressed astonishment at Israel claims that 1.7 million Gaza residents had been warned to leave their homes, asking: "Where in the world can they go?"
Israel has kept its border with Gaza shut tight to the flight of refugees, while Egypt has also maintained the seven-year-old Israeli-led blockade of the Strip by keeping its border closed as well.
Earlier in the day, Israeli Prime Minister Benjamin Netanyahu said that the operation would continue until quiet was restored in southern Israel.
Operation Protective Edge was launched 13 days ago in what Israel said was an attempt to stop rocket fire from the Gaza Strip, which had increased after Israel launched a massive operation in the West Bank that left 10 Palestinians dead, 130 injured, and more than 600 Hamas-affiliated individuals in prison.
The operation, named "Brother's Keeper," was launched in order to find three Israeli teenagers who disappeared in June from the Jewish settlement of Gush Etzion in the West Bank.
Israel blamed Hamas for the kidnapping without any evidence, a charge which the group denied.
