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."

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.

Members of Congress urge US airlines to resume Israel flights
At least 32 members of Congress wrote a letter to the CEOs of American Airlines, Delta Air Lines and United Airlines urging them "to resume flights as soon as possible to Tel Aviv and keep your operations flexible to assist with bringing Americans home and moving innocent civilians out of harm's way."
While U.S.-based airlines have stopped flights to and from Tel Aviv, they have been working with the U.S. government to bolster their operations in Europe to help get fleeing Americans home after they land in European cities.
The lawmakers wrote that certain "barriers" to resuming operations "may seem too complex or too difficult, but as long as there are Americans in need and a way to operate safely -- we must try."

Asked what worries him about ground invasion, Biden says, 'Death'
When a reporter on Friday asked President Joe Biden what worries him about a potential Israeli ground invasion into Gaza, Biden responded, "Death."
UN Secretary-General António Guterres warned earlier Friday that Israel’s call for more than 1 million people to evacuate northern Gaza "is extremely dangerous, and in some cases, simply not possible."
He warned that "hospitals in the south of Gaza are already at capacity and will not be able to accept thousands of new patients from the north."
"The health system is on the brink of collapse; morgues are overflowing," Guterres said at the UN headquarters in New York. "The entire territory faces a water crisis, its infrastructure has been damaged, and there is no electricity to power pumps and desalinization plants."
Israeli forces have postponed the demand to evacuate Gaza's Al Awda Hospital until 6 a.m. local time.

Israel didn't give US heads-up on Gaza evacuation order
While the U.S. and Israel have been coordinating efforts to lessen civilian casualties in Gaza, Israel did not give the U.S. a heads-up on Israel's mass evacuation order for northern Gaza, according to a US official.
"Of course, we're concerned about any additional loss of innocent human life," said John Kirby, spokesperson for the National Security Council.
"We are working very aggressively with the Israelis and the Egyptians to try to find a safe passage out of southern Gaza," he said.

WHO begs for 'immediate reversal of Gaza evacuation order'
The World Health Organization is begging Israel to immediately reverse its evacuation order for the over 1 million living north of Wadi Gaza, saying "a mass evacuation would be disastrous for patients, health workers and other civilians left behind or caught in the mass movement."
"With ongoing airstrikes and closed borders, civilians have no safe place to go," the WHO said in a statement. "Almost half of the population of Gaza is under 18 years of age. With dwindling supplies of safe food, clean water, health services, and without adequate shelter, children and adults, including the elderly, will all be at heightened risk of disease."
"Of the thousands of patients with injuries and other conditions receiving care in hospitals, there are hundreds that are severely wounded and over 100 who require critical care," the WHO said. "Many thousands more, also with wounds or other health needs, cannot access any kind of care. The compressed timeframe, complex transport logistics, damaged roads, and, above all, lack of supportive care during transport all add to the difficulty of moving them."
At least 500 killed in explosion at Gaza hospital: Gaza Health Ministry
At least 500 people have been killed in an explosion at Al Ahli Arab Hospital in the middle of Gaza, according to the Gaza Health Ministry.
The hospital served as a shelter for thousands of residents who fled their homes in northern Gaza.
The Israel Defense Forces denied responsibility for the explosion, saying a failed launch by the Palestinian Islamic Jihad caused the blast.
"From the analysis of the operational systems of the IDF, an enemy rocket barrage was carried out towards Israel, which passed in the vicinity of the hospital, when it was hit," IDF said.
The World Health Organization condemned the blast and called for "the immediate active protection of civilians and health care" workers.
This hospital "was one of 20 in the north of the Gaza Strip facing evacuation orders from the Israeli military," the WHO said in a statement. "The order for evacuation has been impossible to carry out given the current insecurity, critical condition of many patients, and lack of ambulances, staff, health system bed capacity, and alternative shelter for those displaced."
Palestinian Authority President Mahmoud Abbas has declared three days of mourning following the attack.
