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."

State Department says 4,000 seats offered to Americans leaving Israel

A State Department official said Monday night that the department has offered 4,000 American citizens and their immediate family members help to depart Israel via government-organized transportation since Friday.

“Since Oct. 13, we have augmented the limited commercial flight availability by offering more than 4,000 seats on U.S. government-chartered transport by air and sea to U.S. citizens and their immediate family members,” one official said. “We have communicated the availability of departure assistance options for U.S. citizens via targeted, individualized messaging as well as via broad public messaging.”

Departing flights, though, were not nearly at capacity, the official said.

“The departure options we have offered have generally departed at half capacity or less. Nearly 1,000 U.S. citizens and their immediate family members have departed on U.S. government-chartered transport,” an official said.

The official added that 3,000 other American citizens have told the State Department that they were able to leave Israel and the West Bank on their own.
