The Oct. 7 cross-border attack led by Hamas killed some 1,200 people, mostly civilians, and took around 250 others hostage. More than 100 were freed in a weeklong truce the following month. Israel believes at least a third of the over 90 captives still in Gaza are dead.

Israel says it has killed thousands of the armed group’s members and destroyed much of its infrastructure, but since the cease-fire started Hamas has shown it still holds power in the enclave.
