Geneva: Palestinian civilians in densely-populated Gaza have no place to hide from Israel’s military offensive and children are paying the heaviest price, the United Nations said on Tuesday.

“There is literally no safe place for civilians,” Jens Laerke, spokesperson of the UN Office for Humanitarian Assistance (OCHA), told a news briefing in Geneva.

Nearly 600 people have been killed in the coastal enclave, which has an estimated 4,500 people per square kilometre, Laerke said. The priority for aid agencies was protecting civilians and evacuating and treating the wounded.

Nearly 500 homes have been destroyed by Israeli air strikes and 100,000 people have sought shelter in schools of the UN Relief and Works Agency (UNRWA), where they are in need of food, water and mattresses, he said.

Israel began air strikes on the coastal strip on July 8, saying it wanted to halt missile fire out of Gaza by Hamas fighters, and launched a ground offensive last Thursday. Israel pounded targets across the Gaza Strip on Tuesday, dashing hopes of a pause in the fighting. Hamas rejected an Egyptian ceasefire proposal last week.

Twenty-nine Israelis, 27 of them soldiers, have died.

But the overwhelming majority of people killed so far in the conflict are Palestinians, including 121 Gaza children under the age of 18 who make up one-third of the total civilian casualties, Juliette Touma of the UN Children’s Fund (Unicef) said.

More than 900 Palestinian children are also reported to have been injured, according to Unicef.

“According to an assessment by aid workers on ground at least 107,000 children need psycho-social support for the trauma they are experiencing such as death, injury or loss of their homes,” Laerke said.

More than 1.2 million people in the enclave have no water or only limited access to water as power networks have been damaged or lack fuel for generators, he said.

“In addition, we do have reports of sewage flooding which is a threat to public health,” he said.

The World Food Programme (WFP) has distributed emergency food rations and food vouchers to more than 90,000 people so far during the conflict, spokesperson Elisabeth Byrs said.

Supplies from Dubai

“Ready to eat food stocks are running low in Gaza given the conflict has lasted two weeks and the needs are increasing,” she said.

Supplies will be bought locally and also airlifted from Dubai.

The World Health Organisation (WHO) said that 18 health facilities in Gaza have been damaged, including three hospitals.

“There are critical concerns with hospital supplies, as both medicines and medical disposables are in serious shortage, both in ministry of health and NGO hospitals, due to the large number of casualties and serious shortages even before the escalation of violence,” WHO spokesperson Fadela Chaib said.
