Israeli Prime Minister Benjamin Netanyahu has said that he will sue a newspaper over claims he ignored an advance warning about Hamas' October 7 attack.Haaretz published a report claiming Netanyahu was personally alerted by the President of the United Arab Emirates, Sheikh Mohamed bin Zayed, that Hamas was planning a large-scale offensive against Israel a week and a half before the massacre.The report alleges that the Israeli prime minister did not heed the warning, and chose not to brief the heads of the defence establishment, including the head of the Shin Bet, the head of the Mossad, the Israel Defence Forces' chief of staff.The explosive claim, which comes amid a crucial election campaign, followed an investigation by journalists Shlomi Eldar and Ruth Yuval for their new book, 'Hostages: 843 Days of Abandonment'.The prime minister's bureau called the investigation an 'absolute lie', adding: 'Prime Minister Netanyahu didn't speak to the president of the UAE during the period in question and received no warning from him.'The lawsuit will not only target the newspaper but also Eldar, who co-authored the report with Yuval.'A thorough examination not only of the Prime Minister's call log, but also of the records of entries into the Prime Minister's Office during this period, does not show any entry of the Emirati representative into the Prime Minister's Office,' the bureau said. The claim has prompted Israeli opposition leaders to describe the prime minister as 'unfit' for office. Israeli Prime Minister Benjamin Netanyahu has said that he will sue a newspaper over claims he ignored an advanced warning about Hamas' October 7 attackHaaretz claimed that the late Hamas leader Yahya Sinwar, later killed by Israel, had warned a former Palestinian official that the militants were preparing 'a terrifying operation'.Sinwar described the planned attack as an 'earthquake' and 'something extraordinary'.The message was transferred to bin Zayed, who held a 45-minute phone call with Netanyahu at the end of September about Hamas' explicit intention to go to war, the report said.From his Presidential Palace in Abu Dhabi, the Emirati leader allegedly warned the Israeli prime minister that the operation would not only lead to bloodshed, but would destabilise the entire region and undermine the Abraham Accords.To his surprise, Netanyahu reacted with relative calm, the report said. A similar call allegedly reached the prime minister's bureau in those days from the Egyptian intelligence chief, Major General Abbas Kamel, who warned Netanyahu of 'something unusual, a terrifying operation,' about to be launched by the terrorist group.In a meeting with security chiefs on October 1, Netanyahu did not mention the warning calls he had received, Haaretz claimed.At 6.29am, on October 7, Hamas stormed the border and launched its unprecedented attack, resulting in the single deadliest day for Jews since the Holocaust.Militants killed over 1,200 people and took another 251 people hostage during the onslaught. Since then, hundreds of Israelis, mostly soldiers, have been killed in continued fighting from consequent wars in Gaza, Lebanon and Iran. Israel’s retaliatory military offensive has plunged the Gaza Strip into a humanitarian crisis and killed more than 73,000 Palestinians, according to the territory's Hamas-run health ministry - figures considered reliable by the UN.The claims, contained in 'Hostages: 843 Days of Abandonment', are based on dozens of sources in Israel and worldwide, including very senior officials, as well as recordings, internal documents and correspondence, according to the authors.Netanyahu’s office on Tuesday denied that the UAE gave him a warning. 'If there was any relevant information, it was passed through intelligence channels between the two countries,' the statement said. In a joint statement published the same day, several Israeli opposition party leaders announced their intention to find out what the Israeli leader knew and when, and what actions he took, if any.'Why did he not inform the security establishment, and why did he not act to protect Israeli citizens?' the statement said.Gadi Eisenkot, a former military commander who has emerged as Netanyahu's top rival in upcoming October 27 elections, accused the long-serving prime minister of evading responsibility for security lapses and resorting to 'pathetic' excuses, such as saying he was not woken up soon enough on the morning of the attack.'Netanyahu received dozens of warnings for October 7 and ignored them all. He is unfit,' Eisenkot wrote on X.Naftali Bennett, a former prime minister also running in elections, said Netanyahu 'bears personal and direct responsibility' for the deaths on October 7, the deadliest attack in Israeli history.'Netanyahu cannot continue to serve in his position for even one more minute,' Bennett said.The leader of the centre-left Democrats party, Yair Golan, accused Netanyahu of 'endangering Israel'.'The stories about "no one woke me up" are over. You knew, you ignored, you failed, you are to blame,' he said, in a video posted on social media.Many Israelis have demanded an independent state commission of inquiry into the security lapses that failed to prevent the deadly onslaught.Opposition parties say establishing such a commission, whose members would be appointed by the supreme court, would be their first priority if elected into power.Netanyahu’s government has rejected the proposal.The prime minister's office said the report was part of a 'sinister plot with clear political timing, as part of the left's election campaign,' warning that there would be 'more such false plots'.
