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."

The U.S. is sanctioning two groups and 16 people it says enabled Iran's drone production following Iran's attack on Israel last weekend.

"Today, in coordination with the United Kingdom and in consultation with partners and allies, we are taking swift and decisive action to respond to Iran’s unprecedented attack on Israel," Treasury Secretary Janet Yellen said. "We’re using Treasury’s economic tools to degrade and disrupt key aspects of Iran’s malign activity, including its UAV program and the revenue the regime generates to support its terrorism."

The Treasury Department said it’s sanctioning Khuzestan Steel Company, Iran's largest steel producer. The Treasury Department said Iran's metals sector generates "several billion dollars in revenue annually."

The U.S. is also targeting the Iranian carmaker Bahman Group for its role in making vehicles used by the Islamic Revolutionary Guard Corps for military operations.

The sanctions also target people who work for Iran-based drone manufacturers, including executives of the Mado Company, which the U.S. says produced drone engines used in Iran's Shahed UAVs. The U.S. also sanctioned members of the IRGC who it says help supply proxy groups, like the Houthis in Yemen, with drones that have attacked U.S. service members in the Red Sea.

Yellen added that the U.S. would "continue to deploy" sanctions to counter any further action by Iran, with the goal of making it harder and more expensive for Iran to undertake destabilizing actions.

President Joe Biden said in a statement that these sanctions are "holding Iran accountable."

Biden emphasized that the sanctions are in coordination with the international community, and he said the other G7 countries are committed to increasing "economic pressure" on Iran alongside the U.S.

Biden said he has instructed his team to continue to impose sanctions that will degrade Iran's military capabilities.

Biden also reiterated his ironclad support for Israel, and issued a warning to Iran and those who "enable" Iran's attacks.

"We are committed to the security of our personnel and partners in the region," Biden said. "And we will not hesitate to take all necessary action to hold you accountable."
