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.

Hamas and Israel on Saturday accused the other of blocking attempts to strike a Gaza ceasefire agreement, nearly a week into indirect talks between the two sides to halt 21 months of bitter fighting in the Palestinian territory.
