Israel-Gaza updates: Israeli forces preparing for 'wide range of offensive plans'

Fighting is ongoing after Hamas launched an attack on Israel on Oct. 7.

At least 1,400 people have died and 3,400 others have been injured in Israel after the militant group Hamas launched an unprecedented incursion from air, land and sea on Oct. 7, Israeli authorities said.

In Gaza, 3,000 people have been killed and another 12,500 were injured, according to the Palestinian Ministry of Health.

Tensions are high with the prospect of ground war and evacuation orders for Gaza after the Israel Defense Forces called for "all residents of Gaza City to evacuate their homes" and "move south for their protection" early Friday, saying residents should move "and settle in the area south of the Gaza River." The announcement was made, according to the IDF, because it plans to "operate significantly in Gaza City in the coming days" and wanted "to avoid harming civilians."

'Acute security threats' preventing US from aiding Americans at Rafah crossing

As Americans inside Gaza wait for the Rafah border crossing between Egypt and Gaza to open, a senior State Department official said that Egypt has informed the U.S. that “there are acute security threats" preventing U.S. officials and others from aiding Americans inside Gaza.

The official added that the State Department has placed a team on the Egypt side of the border "as close to the border as conditions permit."

Egyptian Foreign Minister Sameh Shoukry said Monday that Israel has not allowed the opening of the Rafah border crossing from the Gaza side.

Shoukry said, since the crisis broke out, Egypt "has been seeking to keep the crossing operational and in a way that allows the entry of humanitarian aid."

"Until now, unfortunately, the Israeli government has not taken a position to allow the opening of the crossing from the Gaza side for the entry of aid or the exit of nationals of [other] countries," Shoukry said. "We are ready and Egyptian authorities on the border are ready to get aid in and get nationals of third countries out."

He added that Egypt aims to keep normal operation of the border "for the entry of Palestinians with medical needs or the normal movement between the Strip and Egypt."
