Israel says the cease-fire could be extended if more hostages are released, and Prime Minister Benjamin Netanyahu's office said it had received a new list of hostages to be released by Hamas on Saturday. Meanwhile, specialised equipment has been deployed to the derailment area to conduct air monitoring. Molten sulphur is known to release sulphur dioxide when it burns, CSX said. During the truce, Israel agreed to allow the delivery of 130,000 liters (34,340 gallons) of fuel per day -- still only a small portion of Gaza's estimated daily needs of more than 1 million liters. The ministry says some 6,000 people have been reported missing, feared buried under rubble. The ministry does not differentiate between civilians and militants in its death tolls. But the hundreds of thousands who evacuated from northern Gaza to the south were warned not to return in leaflets dropped by Israel. Israeli troops hold much of the north, including Gaza City.

Friday's halt in fighting brought Gaza's uprooted population a moment to catch their breath after weeks of fleeing for shelter, searching for food and fearing for family. The hostages included multiple generations. Nine-year-old Ohad Munder-Zichri was freed along with his mother, Keren Munder, and grandmother Ruti Munder. The fourth-grader was abducted during a holiday visit to his grandparents at the kibbutz where about 80 people -- nearly a quarter of all residents of the small community -- are believed to have been taken hostage.

Two cars also carried magnesium hydroxide, but there is no indication that those cars were breached, according to CSX. The others were either empty or carrying non-hazardous products such as grain and plastic. But relief has been tempered -- among Israelis by the fact that not all hostages will be freed and among Palestinians by the briefness of the pause. The short truce leaves Gaza mired in humanitarian crisis and under the threat that fighting could soon resume. Beshear also activated the state’s price-gouging laws to protect families from any grossly overpriced goods and services after the incident, his office announced.

Hours later, 24 Palestinian women and 15 teenagers held in Israeli prisons in the occupied West Bank and east Jerusalem were freed. In the West Bank town of Beituna, hundreds of Palestinians poured out of their homes to celebrate, honking horns and setting off fireworks that lite up the nights sky.The Israeli offensive has killed more than 13,300 Palestinians, according to the Health Ministry in the Hamas-run Gaza government. Women and minors have consistently made up around two-thirds of the dead, though the latest number was not broken down. The figure does not include updated numbers from hospitals in the north, where communications have broken down. The hope is that "momentum" from the deal will lead to an "end to this violence," said Majed al-Ansari, a spokesman for the Foreign Ministry of Qatar, which served as a mediator along with the United States and Egypt. The war erupted when several thousand Hamas militants stormed into southern Israel, killing at least 1,200 people, mostly civilians, and taking scores of hostages, including babies, women and older adults, as well as soldiers. CSX said it would provide Thanksgiving dinner for residents, along with other food, lodging and other necessities..
