By Alexander Cornwell and Nidal al-Mughrabi TEL AVIV/CAIRO (Reuters) -Hamas leaders were due to discuss what U.S. President Donald Trump has called a "final proposal" for a 60-day ceasefire in Gaza on Friday evening,

Momentum for a ceasefire is mounting as the U.S. has stepped up diplomatic efforts in recent weeks, applying pressure to both Israel and Hamas to reach an agreement that also includes a mechanism for the release of the remaining Israeli hostages held in Gaza.

U.S. President Donald Trump says Israel has agreed on terms for a new 60-day ceasefire with Hamas and that Washington would work with both sides during that time to try to end more than 20 months of war in Gaza.
