Israel-Gaza updates: Biden speaks with Netanyahu about hostages' release, Gaza humanitarian assistance
The hostages are two elderly women who are both Israeli nationals.
Thousands of people have died and thousands more were injured after the militant group Hamas launched an unprecedented surprise attack on Israel on Oct. 7 and Israel retaliated with a bombing campaign and total siege of the neighboring Gaza Strip, leaving the region on the verge of all-out war.
At least 1,400 people have died and 4,629 others have been injured in Israel, according to Israeli authorities. In Gaza, 5,087 people have died and 15,273 have been wounded, according to the Palestinian Health Authority.
Aid workers and officials fear that Israel's call for an evacuation of the northern part of Gaza is precipitating a humanitarian disaster as electricity and other supplies have been cut off in preparation for what appears to be an imminent ground offensive.
Humanitarian groups have urged Israel to call off the evacuation and agree to a cease-fire, even as the country has asserted a right to defend itself -- a right the United States endorses.

Gaza hospitals operating at 150% capacity, health ministry says
Gaza hospitals are operating at 150% capacity, with some patients lying on the ground or in corridors, the Gaza Health Ministry said.
Fourteen health centers were forced to stop operations, and all health facilities are at risk of shutting down due to power outages and fuel, the ministry said.
Israeli military has 'green light' to move into Gaza, official says
The Israeli military has a "green light" to move into Gaza whenever it's ready, a member of the country’s security cabinet told ABC News.
Hostages and civilian casualties will be secondary to destroying Hamas, Economy Minister Nir Barakat told ABC News, "even if it takes a year."
Asked about the miles of tunnels Hamas has built under Gaza, he said they’d become the "world’s biggest cemetery." Hamas has claimed to be holding some or all of the 203 Israeli hostages it’s taken within that vast network.
"We shall do all efforts to bring our hostages, to bring our hostages [back] alive…" he said, but the "first and last priority" is destroying Hamas.
Hamas and Islamic Jihad together have about 50,000 fighters, said Agriculture Minister Avi Dichter, former head of Shin Bet, the Israel Security Agency.

State Department issues 'worldwide caution' alert
The State Department on Thursday issued a bulletin for "worldwide caution" because of "increased tensions" around the world and "the potential for terrorist attacks, demonstrations or violent actions."
The State Department warned that Americans abroad should stay alert, enroll in the Smart Traveler Enrollment Program and follow the State Department on social media.
The State Department is instructing its embassies and consulates around the world to conduct emergency security reviews amid ongoing protests sparked by the Israel-Hamas war, according to sources familiar with the matter and documents reviewed by ABC News.
Secretary of State Antony Blinken also instructed personnel to evaluate whether embassies should issue alerts to Americans in their respective countries about threats posed by the demonstrations, as many have already done.
A number of posts have asked the State Department to modify their operations due to security concerns, sources said, but at this point it does not appear that any additional embassies have asked to go on authorized departure, and so far none have requested a full evacuation.
