What to know about the ceasefire between Israel and Hamas

After more than a year of devastating war, the ceasefire between Israel and Hamas is set to begin on Sunday, pausing the 15-month conflict between Israel and the Palestinian militant group in the Gaza Strip.

The deal is the most significant breakthrough in the war, but its implementation is complex and fragile. It requires cooperation between Palestinian militant groups, the International Red Cross, the Israeli military, mediators from multiple countries and an Israeli government whose coalition is starting to fray as hard-line ministers express their disapproval.
