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

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

Israeli Prime Minister Benjamin Netanyahu touched down in Washington on Monday to discuss U.S. diplomatic efforts in the Middle East, including Israel-Hamas cease-fire negotiations. The trip’s centerpiece will be an evening meeting with U.S. President Donald Trump at the White House.
