Negotiations for the second phase of the deal were supposed to be under way before the first phase ends on March 2, but Qatar said the talks have not officially started yet.
A "Hezbollah model" in Gaza would not be acceptable to Israel "and therefore we need a total demilitarisation of Gaza and no presence of the Palestinian Authority", Saar said in a press conference.
He added that Israel was aware of an alternative plan by Arab states for Gaza, made to counter U.S. President Donald Trump's proposal to redevelop the strip under U.S. control, which Israeli Prime Minister Benjamin Netanyahu has said is worthy of exploration.
Israel would not support a plan that would see civilian control of Gaza transferred from Hamas to the Palestinian authority, Saar added.

Israel and Hamas implemented the first phase of a hostage release and ceasefire deal on 19 January 2025. More than 46,000 Palestinians have been killed in the Gaza Strip, according to the Palestinian Ministry of Health, since Israel launched a military campaign in the strip in response to a cross-border attack led by the Palestinian militant group Hamas on 07 October 2023, in which about 1,200 Israelis were killed and more than 250 taken hostage.
