On October 7 2023, Hamas terrorists flooded across the border into southern Israel, killing close to 1,200 people and dragging 251 hostages back to Gaza.
Now, more than 15 months on, Israel says 91 hostages are still being held, 57 of whom are believed to still be alive.
Families have been separated from babies, grandparents, mothers, brothers and friends.
As part of the ceasefire deal between Hamas and Israel that came into effect on Jan 19, Hamas has promised to release the hostages in stages in return for thousands of Palestinian prisoners.
Three female hostages, Emily Damari, 28, Romi Gonen, 24, and Doron Steinbrecher, 31, were released on day one of the truce.
On Saturday, day seven of the ceasefire, Hamas is expected to release four more hostages.
By the 42nd day, 33 hostages – consisting of the young, the old, the sick and the wounded – should be released under the terms of the agreement.
