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."

US reaching out to families of missing Americans

The U.S. has started reaching out to the families of Americans missing in Israel as part of its efforts to identify the U.S. citizens who may be among the hostages taken to Gaza by Hamas, according to an official.

But due to the dynamic situation and lack of visibility inside Gaza, the U.S. still can't say how many may be detained.

There's also a level of reluctance from U.S. officials to shine a spotlight on any Americans among the hostages for fear that they might be singled out by their Hamas captors.

Other sources said American officials are working the phones with allies in the Middle East who have leverage over Hamas, encouraging them to pressure the militants to free the hostages.
