Sources say that mediators trying to reach a peace agreement between Hamas and Israel have spoken to Hamas' military leadership in Gaza and told them they will not accept the new US ceasefire plan.

Hamas' military leadership in Gaza, Izz al-Din al-Haddad, is said to believe the plan is about to hasten the end of Hamas and is determined to fight whether the group accepts it or not.

Israel has accepted President Donald Trump's 20-point Gaza peace plan.

The plan calls for Hamas to disarm and has no role in Gaza's future.

Some Hamas political leaders in Qatar have expressed interest in accepting the plan, but it is said that they have little influence because the group does not have the individuals it has captured.

48 hostages are being held by Hamas, of whom 20 are believed to be alive.

Another factor that has made it difficult for Hamas leaders to agree to the plan is the part of the plan that requires all hostages to be released within 72 hours of the agreed ceasefire.

If this happens, Hamas will have nothing to negotiate with.

Although Trump has assured Israel that it will abide by the plan, there are doubts within Hamas that it will intensify its military campaign after the release of the hostages.
