Qatar will send a delegation of mediators to Cairo on Tuesday to work on negotiations for a cease-fire deal, according to a spokesperson for the Qatari Foreign Ministry.

In a statement, the Qatari Foreign Ministry said they hope "talks will culminate in reaching an agreement for an immediate and permanent ceasefire in the Gaza Strip and the exchange of prisoners and detainees, and the sustainable flow of humanitarian aid into all areas of the Strip."

As cease-fire talks continue, IDF spokesperson Daniel Hagari again warned Palestinians in the eastern part of the city to evacuate.

"Tonight, we also call upon those staying in specific areas which we have communicated and defined through every means -- radio, media, internet, and flyers -- in eastern Rafah, to move towards the expanded humanitarian area in Al-Mawasi and Khan Yunis, where they will receive full humanitarian aid and where water, food, medical equipment, and shelter will be provided,” Hagari said.

Israeli Minister Benny Gantz said in a statement Monday the current proposal put forth by Hamas "has significant gaps.”

"Despite this, we continue to turn over every stone and a delegation will go to Cairo," he added.

Gantz said “every decision will be brought to the war cabinet,” which is made up of Israeli Prime Minister Benjamin Netanyahu, Israeli Defense Minister Yoav Gallant and himself.

National Security Council spokesperson John Kirby told reporters that the U.S. is reviewing the Hamas response to a cease-fire proposal.

Kirby did not reveal many specifics about where negotiations stand, but said they’ve reached a “critical stage.”

“I don't know that it gets any more sensitive than right now,” Kirby said. “And the worst thing that we can do start speculating about what's in it.”

The Israel Defense Forces has announced that it has opened a new crossing to bring humanitarian aid into the famine-stricken Gaza.

The military announced in a Sunday press release the opening of the Western Erez crossing between Israel and northern Gaza in coordination with the U.S.

According to the military, the new crossing is located west of the Erez crossing, closer to the seashore. The crossing was constructed by the Israeli military "as part of the effort to increase routes for aid to Gaza, particularly to the North of the strip."

Earlier Sunday, IDF said it launched a large-scale operation in the area of Jabaliya in the North, while intensifying its military operations in the Eastern portion of Rafah and the Gaza side of the Rafah crossing. It said that it had called on the civilian population to evacuate from Jabaliya to shelters in the west part of Gaza City.
