CIA chief William Burns, Egyptian intelligence chief Abbas Kamel, Qatari Prime Minister Mohammed bin Abdulrahman Al-Thani, and Israeli Mossad chief David Barnea deliberated over the amended plan, which now includes stringent conditions put forth by Israeli Prime Minister Benjamin Netanyahu.

The talks on the revised proposal were relayed to the White House on Saturday, as Netanyahu concluded his visit to the US, where he had been since Monday.

Netanyahu's office expects the discussions to continue in the coming days. However, sources cited by Israeli media warned that Netanyahu’s latest demands could lead to a deadlock in the negotiations.

Israeli reports indicate that the updated terms include demands for an "inspection mechanism" to prevent Hamas fighters from returning to northern Gaza, and for Israel to receive a comprehensive list of all living captives Hamas plans to release as part of the agreement.

Moreover, the proposal suggests that Israel will maintain control over the Philadelphi corridor on the Gaza-Egypt border during the initial stage of the ceasefire and captives' release agreement — a provision vehemently opposed by Cairo.

A senior Israeli official expressed his doubts that the revised proposal would be forwarded to Hamas, citing significant changes that could impede its acceptance.

Meanwhile, an Israeli negotiating team member told Haaretz that the demand for an "inspection mechanism" to prevent Hamas re-infiltration into northern Gaza was “a death blow to the negotiations.”

Israeli media also quoted a Palestinian official who described the updated proposal as Israel’s tactic to effectively reject it while avoiding direct refusal (essentially saying no without literally saying it), suggesting that Netanyahu's amendments were designed to insert roadblocks in the talks.

Accordingly, a senior Palestinian official, quoted by Al-Mayadeen on Saturday, accused Israel of lacking genuine interest in the negotiation process and that Hamas regards any new proposal as "dead on arrival."
