Israeli sources said the army received intelligence signals that there were preparations the night before the attacks from the besieged Gaza Strip, but that they were not taken into account.
Israeli military spokesman Daniel Hagari said: "There was no concrete intelligence warning about this incident, there was a set of intelligence signals the night before, but not about such a move."
This came in his assessment of criticism of the existence of security weaknesses during the "Al-Aqsa flood" attacks by Palestinian factions on settlements around Gaza on October 7.
Israel's Channel 12, citing senior sources, said there were indications that something might happen on the eve of the Hamas attack, but they were not taken into account.
Haghari reported that the army targeted the homes and bases of the elite forces of the Qassam Brigades, which participated in attacks on Israeli settlements surrounding the Gaza Strip.
He confirmed that the Israeli army is making preparations in anticipation of a possible attack from the north on the border with Lebanese territory where Hezbollah is active.
At dawn on Saturday, Hamas and other Palestinian factions in Gaza launched Operation Al-Aqsa Flood in response to the ongoing attacks by Israeli forces and settlers against the Palestinian people, their properties and holy sites, especially the Al-Aqsa Mosque in occupied East Jerusalem.
On the other hand, the Israeli army launched Operation Iron Swords, and continues to launch intensive raids on several areas in the Gaza Strip, which is home to more than two million Palestinians suffering from deteriorating living conditions, as a result of the Israeli blockade that has been ongoing since 2006.
