The Israeli military says that 239 people are being held hostage by Hamas.
Four hostages have been released and another was freed by Israeli forces. Ori Megidish, an Israeli solider, was freed during ground operations in Gaza on 29 October. Two women, Nurit Cooper and Yocheved Lifschitz, were freed on Monday 24 October. On Friday 20 October, two US hostages - a mother and daughter - were also freed.
Israel now says that the bodies of two hostages - Noa Marciano and Yehudit Weiss - have been found near Al-Shifa hospital in Gaza.
Hamas says it has hidden the hostages in "safe places and tunnels" within Gaza. Israel Defense Forces (IDF) have previously said the hostages include 20 children and between 10 and 20 over-60s.
The IDF have notified some families that their loved ones are being held hostage, while other families - whose relatives remain unaccounted for - believe they have been taken.
These are the stories of hostages taken from Israel on 7 October which have been either confirmed by the BBC or credibly reported.
