Israel and Hamas have been negotiating over a peace deal which would bring a temporary halt to fighting and allow hostages to be released.
Drafts of the deal negotiated with international partners including the US show 10 Palestinian prisoners held in Israel could be released in exchange for every hostage held in Gaza.
The agreement would stop short of fulfilling Hamas’ main demand for a permanent end to the war.
The deal says Hamas will agree to release all women, children, elderly and wounded captives, but stops short of covering men of fighting age.
One of the key aims is to have a ceasefire deal in place in time to stop fighting for the holy Muslim month of Ramadan, which begins on March 10.
