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."

U.S. Secretary of State Antony Blinken on Sunday said the Biden administration is working to verify reports that U.S. citizens are among the dead and missing in Isreal following Saturday's unprecedented attacks from Hamas into Israel from Gaza.
“We have reports that several Americans were killed. We are working overtime to verify that,” Blinken told CNN's "State of the Union. "There are reports of missing Americans."
Blinken called the attack the worst since the 1973 Yom Kippur War, but added that there is a "fundamental difference."
"That was a war that was state-to-state, country-to-country, army-to-army. This is a massive terrorist attack that is gunning down Israeli civilians in their towns and their homes," Blinken said. "As we've seen so graphically, they're literally dragging people across the border with Gaza, including a Holocaust survivor in a wheelchair, women and children. You can imagine the impact this is having throughout Israel and the world should be revolted at what it's seen."
