Israel-Gaza updates: Crossing closed to aid after rockets fired from Rafah: IDF

Osama Hamdan, a senior Hamas official, said in a statement that cease-fire negotiations with Israel will cease if it moves forward with its operation into Rafah.

"The Israeli enemy is trying to blackmail everyone with the Battle of Rafah," he said in a statement.

Hamdan told Lebanese TV late Wednesday that a cease-fire deal had not been reached and Hamas was still "studying the swap deal proposal."

"We have substantial notes on the proposal," Hamdan told Lebanese TV.

"We are studying the proposal and we will respond to it in a way that serves our goals."

The humanitarian pier being constructed off the coast of Gaza by U.S. soldiers is over 50% complete, deputy Pentagon press secretary Sabrina Singh told reporters Wednesday.

The pier, known as JLOTS, is on track to meet the early May time frame for delivery, she said.

"The floating pier has been completely constructed and set up. The causeway is in progress," she said.

Singh said the United Nations will be responsible for distributing the aid once the pier is open, and that the drivers of the delivery trucks will be from a third party and not U.S. forces.

When asked how security will be handled to prevent strikes on aid workers, Singh said the Israel Defense Forces "has shown that they are taking steps to mitigate that from happening again."

Jordan's foreign ministry alleged Israeli settlers attacked two of its humanitarian aid convoys that were en route to Gaza Wednesday.

Hussein Al-Shebli, the secretary general for the Jordan Hashemite Charity Organization, said in a statement that his organization sent a convoy of 97 trucks to two locations: the Beit Hanoun border crossing and Karam Abu Salem.

Al-Shebli claimed there were attempts "by many of the settlers and from the Israeli side, from Israeli citizens," to prevent the arrival of the convoy at the crossings.

"The aid trucks were attacked, by trying to break them and the cutting of their air pipes," he said in a statement.

Ultimately, the trucks were able to arrive at the crossings, according to Al-Shebli.

Israeli officials have not immediately commented on the allegations.

Hamas is expected to submit a response to Israel's current hostage and cease-fire deal proposal "within hours," a senior Egyptian official told ABC News Wednesday.

The official said efforts to broker a cease-fire deal between Israel and Hamas are proceeding in a “positive atmosphere."

“Negotiations are continuing with all sides to resolve a number of sticking points," the official added.

Secretary of State Antony Blinken urged Hamas to accept the terms of the cease-fire deal.

"Israel has made very important compromises in the proposal that is on the table, demonstrating its desire and willingness to get this agreement and get it done," he said while at the Port of Ashdod.

"There is no time for delay. There's no time for further haggling. The deal is there. They should take it," he added.
