Israel-Gaza updates: IDF releases Hamas 'psychological terror' video of young hostages

The Biden administration notified Congress on Tuesday that it is moving forward with more than $1 billion in new weapons deals for Israel, according to sources familiar with the matter at the White House and on Capitol Hill.

National Security Advisor Jake Sullivan told reporters Monday that the United States is continuing to send military assistance to Israel. The only shipment paused involves the 2,000-pound bombs, for fear they'd be used in a major invasion in Rafah, according to a U.S. official.

About 450,000 Palestinians have been displaced from Rafah, fleeing to safety, according to the U.N. Relief and Works Agency for Palestine Refugees in the Near East.

"Inland in Rafah is now a ghost town. It’s hard to believe there were over one million people sheltering here just a week ago,” UNRWA spokesperson Louise Wateridge said. "People face constant exhaustion, hunger and fear. Nowhere is safe. An immediate ceasefire is the only hope."

The development comes as airstrikes continued to hit northern and southern Gaza Tuesday. The Israeli military said it had hit 120 targets in the last 24 hours.

The International Court of Justice said it will hold hearings over Israel's attacks on Rafah during the war in Gaza, after South Africa sought new emergency measures as part of its ongoing case accusing Israel of violating the Genocide Convention in its offensive on Gaza.

Hearings will be held on Thursday and Friday in the Hague.

South Africa first brought the case before the ICJ in December alleging Israel violated its obligations in its offensive with regard to Palestinians in the Gaza Strip.

National security adviser Jake Sullivan stressed the U.S. is working "urgently and relentlessly" to get a hostage deal in place, but did not have any major progress to share Monday.

Sullivan noted that he met with the families of American hostages this past Friday, and that "they know how hard the president is working on this."

On where the hostage negotiations stand currently, Sullivan turned to the architect of the Good Friday agreement in Ireland.

"Sen. [George] Mitchell said quite famously, "'Negotiations are 1,000 days of failure and one day of success.' And right now, we're in the former days rather than the latter day," he said.

"[T]here could be a cease-fire tomorrow if Hamas simply released women, wounded and elderly hostages, all innocents. Israel put a forward-leaning proposal on the table for a cease-fire and hostage deal. The world should be calling on Hamas to come back to the table and accept a deal," Sullivan said.
