US President Donald Trump's envoy and son-in-law, Jared Kushner, returned to Israel on Monday as mediators face new obstacles in advancing negotiations for a fragile Gaza ceasefire. Key sticking points remain unresolved, including Hamas's disarmament, reconstruction of Gaza, and the deployment of an international security force.

Without a timeline for discussions likely requiring significant concessions from both parties, doubts linger regarding potential progress. Additionally, reports have surfaced concerning numerous Hamas fighters believed trapped in tunnels beneath Rafah, complicating negotiations further.

Last week, US special envoy Steve Witkoff indicated that an amnesty might be possible for fighters willing to disarm, although this number remains unconfirmed. Reports suggest Kushner and Israeli Prime Minister Benjamin Netanyahu discussed these concerns during their recent meetings in Jerusalem.

Hamas has demanded safe passage for the trapped fighters, a plea that has so far been rejected by Israel. Both sides have accused each other of violating ceasefire conditions amid ongoing conflict.

The ongoing war stemmed from a Hamas attack on southern Israel earlier this month. Since then, the conflict has resulted in significant casualties, with over 69,000 people reported dead in Gaza alone. The initial ceasefire phase focused on halting violence and ensuring humanitarian aid but has faced various challenges.

As negotiations continue, the prospect of a de-facto partition of Gaza seems increasingly likely, raising concerns about the future governance and political landscape of the region.
