'Vicinity' of U.N. school in Gaza struck by shelling, officials say

 Yet another attack near a U.N.-run school in southern Gaza led to more deaths as the conflict between Israel and Hamas rages on.

At least 10 people were killed and several others wounded Sunday in the attack, the spokesman for the Palestinian Health Ministry in Gaza said.

"I can confirm a shelling incident has caused multiple deaths and injuries in the vicinity of a school," Gunness told CNN's New Day on Sunday morning. "I am not saying it was a direct hit, and we are not confirming who it's by yet. We hope to have more details later."

The IDF has not yet commented on the reported attack. And it was unclear if the school was targeted, directly impacted or if shells fell nearby.

But at least one other U.N.-run school in Gaza has been pounded by violence in the past week.

And the deaths continue to mount. At least 1,756 people have been killed in Gaza since the current Israel-Hamas conflict began July 8, according to el-Qedra. In Israel, 64 soldiers and three civilians have been killed.

Palestinian officials warned of a public health disaster because of the lack of water, sanitation and primary health care.
