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.

As they meet for the third time this year, the outwardly triumphant visit will be dogged by Israel's 21-month conflict against Hamas in Gaza.

Cease-fire talks between Israel and Hamas stall amid hostage disputes, political tensions, and aid access issues.
