Hamas militants killed an estimated 1,200 people and kidnapped 250 others in the October 7 raid. An Israeli air and ground offensive has killed over 28,000 Palestinians, according to local health officials, displaced over 80% of the population and led to a massive humanitarian crisis.Over 100 hostages were freed during a weeklong cease-fire in November. Israel says about 100 hostages remain in Hamas captivity, while Hamas is holding the remains of roughly 30 others who were either killed on October 7 or died in captivity. Three hostages were mistakenly killed by the army after escaping their captors in December.
