People went to Hostages Square in Tel Aviv following President Trump’s announcement
We’ve been tracking the status of Gaza hostages since Hamas attacked southern Israel on 7 October 2023, when around 1,200 people were killed and 251 taken captive. In addition, four hostages were already being held by Hamas, bringing the total in Gaza to 255.
Of the 48 still being in held in Gaza, 20 hostages are believed to be alive.
Just under three-quarters of those still alive are men in their 20s and just over half had been at the Nova Music Festival when it was attacked by Hamas-led fighters.
Those alive are expected to be returned first, possibly as soon as Sunday.
CNN has reported that Israeli sources say the whereabouts may be unknown, external for as many as 15 of the remaining dead hostages.
We will wait for official confirmation before updating our records about the status of all the remaining hostages.
Our three-person team has maintained and updated a database, used to avoid duplication and error across BBC News output, whenever significant new information becomes available.
This could be statements from the Hostages and Missing Families Forum or reliable news reporting, often attributed to family members.
