At least 30 people have been killed and over 100 others injured in an IDF airstrike on the Khadija school in Deir al-Balah -- also a field hospital, according to the Hamas-run Gaza Ministry of Health.

The school is inside the humanitarian safe zone designated by the Israel Defense Forces. The IDF accused Hamas of using the school as a "command and control center."

Video reviewed by ABC News shows people running through dust. A woman with blood covering her hands and face chases after a man holding an unconscious child. Several bodies are visible on the ground.

An aide to the vice president pushed back Friday on Israeli Prime Minister Benjamin Netanyahu seeming to suggest Harris' public comments following their meeting a day earlier could have an impact on cease-fire negotiations.

"Well, we're trying to get one. And I think to the extent that Hamas understands that there's no daylight between Israel and the United States, that it expedites the deal. And I hope that those comments don't change that," Netanyahu told reporters when asked about her comments.

Harris' aide said in a statement there is no daylight between Harris and Biden's views.

"President Biden and Vice President Harris delivered the same message in their private meetings to Prime Minister Netanyahu: It's time to get the ceasefire and hostage deal done. And this is what the Vice President said publicly as well," the aide said.

"The public comments tracked with her previous comments on the conflict. She started with rock-solid support for Israel and then she expressed her concern about civilian causalities and the humanitarian crisis in Gaza, as she always does," the aide added.

Senior Egyptian security officials will meet their American and Qatari counterparts in the presence of the head of Israel's Mossad intelligence service in Rome on Sunday to discuss a Gaza cease-fire and hostage release deal, a senior Egyptian source said.

The meeting is part of mediation efforts to reach a truce agreement in the Gaza Strip, the source said.

Egypt stressed to all parties taking part in the Rome meeting its commitment in reaching an agreement that requires an immediate cease-fire and ensuring the entry of humanitarian aid into Gaza, the source added.

President Joe Biden is temporarily protecting some Lebanese nationals from deportation and authorizing work permits amid deteriorating humanitarian conditions in southern Lebanon "due to tensions between Hezbollah and Israel," the White House said in a statement Friday.

"I have determined that it is in the foreign policy interest of the United States to defer for 18 months the removal of any Lebanese national" with exceptions, Biden said.

Lebanese nationals who return to Lebanon after the announcement, have not continually resided in the U.S., or have been convicted of a felony or of two misdemeanors are some of the people excluded from the memorandum.
