Hamas is reviewing a proposal agreed at a meeting in Paris last week between Israel, the United States and mediators from Egypt and Qatar, the most serious push for a ceasefire since the last truce collapsed after a week in November.

A senior source close to the talks told Reuters that the draft proposal sent to Hamas was for a 40-day truce during which Hamas would free around 40 hostages - including women, those under 19 or over 50 years old, and the sick - in return for around 400 Palestinian detainees at a 10-for-one ratio.

Israel would reposition its troops outside of settled areas. Gaza residents, apart from men of fighting age, would be permitted to return home to areas previously evacuated, and aid would be ramped up, including urgent equipment to house the displaced.
