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."

On the morning of Oct. 7, sirens echoed across Israel as Hamas terrorists began a full-fledged surprise attack from the air, sea and ground. Hundreds of armed Hamas fighters stormed into Israel from Gaza, charging into cities and gunning down citizens.
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.

Fabrizio Carboni, regional director for Near and Middle East for the International Committee of the Red Cross, said hospitals are losing power as Gaza loses power, risking the lives of the elderly on oxygen and newborns in incubators.
"Kidney dialysis stops, and X-rays can’t be taken," Carboni said. "Without electricity, hospitals risk turning into morgues."
Defense Secretary Lloyd Austin told reporters in Brussels Thursday that the U.S. is not placing conditions on its military aid to Israel.
Austin said Israel is "a professional military led by professional leadership" and "we would hope and expect that they would do the right things in the prosecution of their campaign."
Austin said U.S. intelligence had no indication or warning that Hamas was planning such an attack.
Echoing other administration officials, Austin said, "We've not seen any indication that Iran was involved in the planning or the execution of this attack," though he added the U.S. will continue to focus on whether that is truly the case.
Austin said that the U.S. will "work urgently to get Israel what it needs to defend itself," including munitions and Iron Dome interceptors, and said helping Israel won’t affect the U.S. flow of military aid to Ukraine.
