Fifty-one out of the 101 hostages still being held by Hamas in the Gaza Strip are alive, according to the latest Israeli intelligence assessments.

Given the intense military pressure on Gaza and the harsh conditions the hostages have endured for over a year, officials fear the actual number of survivors might be even lower.

During a closed-door session with the Knesset Foreign Affairs and Defense Committee in September, Israeli Prime Minister Benjamin Netanyahu revealed that roughly half the hostages were believed to be alive.
