GENEVA - Large groups of women and children are scavenging for food among mounds of trash in parts of the Gaza Strip, a U.N. official said on Friday following a visit to the Palestinian enclave.

Ajith Sunghay, head of the U.N. Human Rights office for the Occupied Palestinian Territories, expressed concern about the levels of hunger, even in areas of central Gaza where aid agencies have teams on the ground.

"I was particularly alarmed by the prevalence of hunger," Sunghay told a Geneva press briefing via video link from Jordan. "Acquiring basic necessities has become a daily, dreadful struggle for survival."

Sunghay said the U.N. had been unable to take any aid to northern Gaza, where he said an estimated 70,000 people remain following "repeated impediments or rejections of humanitarian convoys by the Israeli authorities".

Sunghay visited camps for people recently displaced from parts of northern Gaza. They were living in horrendous conditions with severe food shortages and poor sanitation, he said.

"It is so obvious that massive humanitarian aid needs to come in – and it is not. It is so important the Israeli authorities make this happen," he said. He did not specify the last time U.N. agencies had sent aid to northern Gaza.

U.S. WARNING

U.S. Secretary of State Antony Blinken and Defense Secretary Lloyd Austin set out steps last month for Israel to carry out in 30 days to address the situation in Gaza, warning that failure to do so may have consequences on U.S. military aid to Israel.

The State Department said on Nov. 12 that President Joe Biden's administration had concluded that Israel was not currently impeding assistance to Gaza and therefore was not violating U.S. law.
