Israel put forward a new cease-fire proposal and hostage release deal on Monday, which has now been passed on to Hamas, an Egyptian security source told ABC News.

Mediators are awaiting a response from Hamas within 24 hours, the source said.

This is the first time Israel has taken the first move to submit a draft proposal since the war began, according to the source. Previous proposals have been initiated by Egyptian and Qatari mediators.

The source said talks could resume soon, without providing an exact timeline.

Vice President Kamala Harris weighed in on the IDF strike in Rafah that killed 50 civilians and injured 249 more, saying, "The word 'tragic' doesn't even begin to describe it."

She did not comment when asked if this crosses a red line for the administration. President Joe Biden has yet to weigh in.

The flow of humanitarian aid for Gaza over the U.S. Army’s temporary Joint Logistics Over-the-Shore (JLOTS) system has paused after rough seas caused parts of the pier to detach, a U.S. official told ABC News on Tuesday.

“Due to high sea states in the North African weather system earlier today, a portion of the Trident pier separated from the pier that is currently anchored into the coast of Gaza. As a result, the Trident pier was damaged, and sections of the pier need rebuilding and repairing,” she said.

The pier will be removed from its place near the Gazan coast and towed back to Ashdod “over the next 48 hours,” where U.S. Central Command will make repairs, according to Singh.

“The rebuilding and repairing of the pier will take at least over a week,” Singh said, adding that after repairs, it will need to be re-anchored to the Gazan shore.

Remarking on the deadly Rafah strike that killed 50 Palestinians and injured 249 others, the Israel Defense Forces said “a fire ignited tragically taking the lives of Gazan civilians nearby,” in a statement Tuesday.

“Sadly, following the strike, due to unforeseen circumstances, a fire ignited tragically taking the lives of Gazan civilians nearby. Despite our efforts to minimize civilian casualties during the strike, the fire that broke out was unexpected and unintended,” IDF spokesperson Rear Adm. Daniel Hagari said.

“This is a devastating incident which we did not expect. We are investigating what caused the fire that resulted in this tragic loss of life,” he added.

Hagari said earlier that the strike had killed the two Hamas commanders they targeted.

The Israeli Defense Forces (IDF) claimed two top Hamas officials were killed in the deadly airstrike in western Rafah Sunday night.

The IDF said Hamas' Chief of Staff in the Judea and Samaria wing, Yassin Rabia, and an additional senior Hamas official, Khaled Nagar, were both killed.

"Hamas' Judea and Samaria wing is responsible for the planning, funding, and carrying out of terror attacks throughout Judea and Samaria and within Israel," the IDF said in a statement Sunday.

The IDF claimed Rabia was responsible for "numerous murderous terror attacks, including in 2001 and 2002, in which IDF soldiers were killed."

The IDF also claimed Nagar "directed shooting attacks and other terrorist activities in Judea and Samaria, and transferred funds intended for Hamas' terrorist activities in the Gaza Strip."

"Previously, Khaled Nagar carried out several deadly terror attacks between 2001-2003 which led to the deaths of several Israeli civilians and the injury and death of several Israeli soldiers," the IDF claimed.

The airstrike in Rafah on Sunday also resulted in the deaths of at least 50 individuals, including civilians, according to Action Aid UK.
