Evidence

Multiple mainstream outlets (Ynetnews, The Times of Israel, The Jerusalem Post, Yahoo News/JFeed, NewsBeep) reported in late September 2026 that former Palestinian Authority minister Sufian Abu Zaida, in a televised interview on the Al-Ghad/Al-Rad channel, said Yahya Sinwar dictated a handwritten note to him on September 14, 2023, warning that an 'earthquake' (zilzal) was coming in the negotiations and that Israel should 'prepare to empty the prisons.' Abu Zaida displayed the note on camera and described relaying it to Israeli officials, who he says questioned him urgently the next morning. Ynetnews notes the wording closely matches previously reported classified intelligence disclosed by Yedioth Ahronoth journalist Ronen Bergman about a pre-October 7 warning. No independent forensic verification of the note itself was reported, and this account rests on Abu Zaida's own testimony rather than independent corroboration of the document's authenticity. No fact-checking organization (Reuters Fact Check, AFP Fact Check, Bellingcat, EUvsDisinfo) verdict on this specific claim was found in searches.
