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.
