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."

State Department confirms Americans are missing, unknown if any are hostages
The State Department confirmed Monday evening that there are still missing Americans in Israel but couldn't immediately provide an exact number or estimate.
The department couldn't say yet if any of the missing Americans were hostages.
White House spokesperson John Kirby echoed this sentiment to ABC News' Linsey Davis.
"We don't really know whether they're just missing somewhere, or are lost, or whether they're being held hostage. I think we have to accept the possibility that at least some of them are being held hostage by Hamas," he said.
Of the Americans previously confirmed dead, a State Department official said they were all thought to be dual U.S.-Israeli citizens primarily residing in Israel.
Staffers at the U.S. Embassy in Israel are fully accounted for and are communicating with impacted Americans around the clock over the telephone and via the online form the department launched for U.S. nationals who believe their family members are among those missing, according to the agency.
The State Department is also urging Americans in the affected areas who are safe to contact their loved ones directly and/or update their status on social media.

The Israel Defense Forces said over 1,500 military targets were hit in Gaza on Monday.
The death toll has continued to grow on both sides as Israeli forces strike back at Gaza's militant Hamas rulers.
At least 11 Americans killed, more may be among those held by Hamas
At least 11 Americans are among those killed in Israel, President Joe Biden said in a statement.
He added, "While we are still working to confirm, we believe it is likely that American citizens may be among those being held by Hamas."
"American citizens still remain unaccounted for, and we are working with Israeli officials to obtain more information as to their whereabouts," Biden said. "My heart goes out to every family impacted by the horrible events of the past few days. The pain these families have endured, the enormity of their loss, and the agony of those still awaiting information is unfathomable."
"I have directed my team to work with their Israeli counterparts on every aspect of the hostage crisis, including sharing intelligence and deploying experts from across the United States government to consult with and advise Israeli counterparts on hostage recovery efforts," Biden said.
Rafah crossing on Egypt's border to open at 9 a.m. Monday
The U.S. State Department has said it believes the Rafah crossing, which is located on the border of Gaza and Egypt, will be open on Monday morning.
Quoting media reports, the State Department said the crossing will open at 9 a.m. local time.
"We anticipate that the situation at the Rafah crossing will remain fluid and unpredictable and it is unclear whether, or for how long, travelers will be permitted to transit the crossing," the State Department wrote in a post on X (formerly Twitter). "If you assess it to be safe, you may wish to move closer to the Rafah border crossing – there may be very little notice if the crossing opens and it may only open for a limited time."
