The UN agency for Palestinian refugees (UNRWA) says an estimated number of 508 displaced people who took shelter in UNRWA centers have been killed and nearly 1600 other injured amid Israeli war on the besieged Gaza Strip.

UNRWA said that it continued to verify the number of casualties caused by incidents that impacted its installations, and notes that these figures do not include some reported casualties where the number of injuries could not be determined.

Earlier Tuesday, Yasmina Guerda of the UN humanitarian agency OCHA described children who lost limbs in Israel’s attack on Nuseirat refugee camp earlier this month that killed at least 274 people and injured more than 700.

“Many of whom reminded me of my own two little toddlers. They were staring into the void, too shell-shocked to produce a sound or a tear,” she said.

She said aid workers were trying to “quantify the suffering with figures”, looking at the total number of displaced people, the liters of water they get per day, or the truckloads of aid that make it across the border.

She pointed out that more than 200 humanitarian relief workers have been killed in Gaza since October 7.
