A UNICEF spokesperson on the ground in Gaza told ABC News Live she is "shocked" by the conditions she has seen in hospitals, including malnourished children.

The spokesperson, Tess Ingram, said she recently visited Al-Aqsa Hospital in central Gaza and met a 7-year-old boy who was "eating grass."

"He was so sick and in so much pain," Ingram told ABC's Terry Moran Thursday. "Thankfully, the doctors there think he will make a full recovery, but he is one of hundreds of children they said that they're treating for malnutrition at the moment."

"This has to be unacceptable, particularly when the aid is just a few kilometers away, as is the nutrition treatments that we have that can save children's lives," she added.

Asked how to protect those providing humanitarian resources in Gaza, following the Israeli airstrike on an aid convoy that killed seven World Central Kitchen aid workers earlier this week, Ingram said "it's called international humanitarian law."

"That is what we are calling on the parties to the conflict to respect," she said.

Officials from humanitarian organizations operating in the Gaza Strip stressed to reporters Thursday that they believe the Israeli airstrikes that killed seven World Central Kitchen aid workers on Monday is part of a pattern.

They said other humanitarian workers were targeted and killed before, including doctors, nurses and journalists, but they were Palestinians.

"The condemnation for the World Central Kitchen incident is right and just, but where is it for every other humanitarian worker, for every other hospital that is destroyed, for every attempt to manipulate the media?" said Christopher Lockyear, secretary general of Doctors Without Borders / Médecins Sans Frontières. "What happened to [World Central Kitchen] is part of a pattern. ... This is about impunity and total disregard of rules of war."

Asked if the World Central Kitchen attack will significantly decrease humanitarian work in Gaza, Lockyear responded, "We remain present in Gaza, but we are assessing the risks on a daily basis."

President Joe Biden spoke Thursday with Israeli Prime Minister Benjamin Netanyahu, their first conversation since seven aid workers from World Central Kitchen were killed in Israeli airstrikes in Gaza.

Biden had strongly condemned the incident, which Israel's said was unintentional, saying he was "outraged."

Biden further expressed to Netanyahu that the strikes on the food relief workers and the overall humanitarian crisis in Gaza are "unacceptable," according to a White House readout of the call.

For the first time, the White House hinted the president may consider a change in U.S. policy with respect to Gaza if Israel doesn't take action to better protect civilians and aid workers.

"He made clear the need for Israel to announce and implement a series of specific, concrete, and measurable steps to address civilian harm, humanitarian suffering, and the safety of aid workers," the readout read. "He made clear that U.S. policy with respect to Gaza will be determined by our assessment of Israel’s immediate action on these steps."

National security adviser Jake Sullivan will meet families of hostages at the White House on Monday, which is one day after the war reaches the six-month mark, a senior administration official said.

President Joe Biden on Friday wrote letters to the president of Egypt and the emir of Qatar on the state of the talks, and he urged them to secure commitments from Hamas to agree to and abide by a deal, the official added.

"The president made clear that everything must be done to secure the release of hostages, including American citizens, now held by Hamas terrorists for nearly six months," the senior administration official said.

"They discussed the importance of fully empowering Israeli negotiators to reach a deal, which in its first phase would secure the release of women, elderly, sick and wounded hostages," the official said.

A new round of talks will take place this weekend in Cairo.
