Israel and Hamas are believed to have agreed that 10 living hostages and the remains of 18 others should be released during the first 60 days of a cease-fire, but they have not reached a consensus on how many Palestinian prisoners should be freed during the same period. Up to 20 hostages are still thought to be alive.

Israeli Prime Minister Benjamin Netanyahu is in Washington Monday to meet U.S. President Donald Trump, who has been pushing for a ceasefire that might lead to an end to the 21-month war in Gaza. Israel and Hamas are considering a new U.
