Israel-Gaza updates: 22, including 18 children, reported dead in Rafah strikes

Senate Minority Leader Mitch McConnell is claiming President Joe Biden is caving to political pressure on Israel.

McConnell criticized Biden for expressing outrage at the deaths of the seven World Central Kitchen aid workers, who were killed in an Israeli strike in Gaza last week, after his administration had called it a tragic accident.

"[That] begs the question whether he's also outraged at the way Israel's cherished aggressors violate international law by turning hospitals and schools [in Gaza] into fighting positions," McConnell said Tuesday. "Instead of welcoming Israel's swift investigation and efforts to hold personnel accountable for their mistakes -- accountability that has been sorely lacking during President Biden's own administration -- the president caved further to domestic political pressure. He indulged his radical base."

Vice President Kamala Harris will meet with the families of American hostages being held by Hamas on Tuesday afternoon, according to the White House.

Harris will "express her continued support for these families and the hostages and will provide an update on our administration’s efforts to broker a deal to secure the release of all hostages and an immediate cease-fire," a White House official said.

National security adviser Jake Sullivan met with the families on Monday.

The families told Sullivan they were appreciative of the Biden administration’s support, but also disappointed that a deal still hadn’t been reached to bring home the remaining hostages, which include eight American-Israeli citizens, the Hostages Families Forum Headquarters said.

The families said they told Sullivan they’re worried their loved ones will be the next to die if the negotiators don’t reach a deal soon.

The Israel Defense Forces said its fighter jets struck and killed Hatem Alramery, the head of Hamas' Emergency Bureau, in Gaza on Monday night.

Hamas said civilians were also killed in the strike.

Hamas officials are accusing the Israelis of being "stubborn" during the latest round of negotiations in Cairo.

"Despite this," Hamas officials said in a statement, Hamas leaders are "studying the submitted proposal … and will inform the mediators of its response once this is completed."

CIA Director Bill Burns presented a new hostage/cease-fire proposal in Cairo this weekend, which included an initial release of 40 hostages in exchange for six-week cease-fire, a source familiar with the negotiations told ABC News.
