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."

Israeli forces responded by sending wave after wave of bombs into Gaza, killing thousands, trapping civilians and raising fears of a wider conflict in the Middle East.

They're facing a shortage of drugs, medical supplies and fuel for generators, according to MSF, as well as the challenge of safely transporting patients to facilities.

"Ambulances can't be used right now because they're being hit by airstrikes," Darwin Diaz, MSF medical coordinator in Gaza, said.

Israel cuts off Gaza in 'total siege'

Israeli Defense Minister Yoav Gallant announced Monday that he has ordered a "total siege" of the neighboring Gaza Strip, allowing no food, fuel or electricity to enter the Hamas-ruled territory.

"We are fighting barbaric terrorists and we will act accordingly," Gallant said.

Since Saturday's surprise attack on Israel launched by Hamas militants, Israeli forces have struck back. Hundreds of buildings and homes have been destroyed in Gaza, leaving more than 123,000 people displaced, according to the United Nations.

Unlike Israel, the Gaza Strip has no air raid sirens or bomb shelters. Over 73,000 people are currently sheltering in schools, according to the U.N.

Meanwhile, hospitals in Gaza are struggling to cope with the number of casualties, the U.N. said. At least 493 people have died and another 2,751 have been injured there, according to the Palestinian Ministry of Health.
