Once these issues are resolved, a three-stage ceasefire could be concluded within days, they added.
The deal would include an exchange of 20 Palestinian prisoners for every female soldier released during the first of three stages of the ceasefire.
The names of the prisoners have yet to be agreed, but they will be chosen from around 400 names serving prison sentences of 25 years or more in Israel.
These do not appear to include senior Fatah leader Marwan Barghouti, whose release Israel is expected to veto.
The Israeli hostages would be released in stages, as it appears Hamas has yet to locate some of the missing hostages.
Of the 96 hostages still held in Gaza, Israel considers that 62 are still alive.
Gaza civilians could return to the north, under a system monitored by Egypt and Qatar, and around 500 trucks a day would bring aid to the strip, the official said.
In the final stage of the three-phase plan, which would see the end of the 14-month war, Gaza would be overseen by a committee of technocrats from the enclave, who would have no previous political affiliations but would have everyone’s support. Palestinian factions.
