This is a list of notable engagements during the Gaza war, encompassing land, naval, and air engagements, covering events which took place or began during the October 7 attack and immediately afterwards, including Israel's declaration of war on 8 October, the imposition of the 2023 Israeli blockade of the Gaza Strip, and active operations in the Gaza Strip. It also covers other engagements in and around Israel directly related to its conflict in Gaza, including Israel's operations in occupied West Bank and southern Syria, support for Palestinian militants from Hezbollah in Southern Lebanon, and intensified attacks on commercial vehicles by Houthi movement in the Red Sea.
Early in the morning of 7 October 2023, approximately 3000 militants, from Hamas, Palestinian Islamic Jihad, the PFLP, and DFLP, breached the Gaza fence and attacked multiple locations in Southern Israel. After the IDF repelled most of the attacks, the militants retreated back into Gaza Strip with multiple hostages captured.
After the attack carried out by Hamas militants, Israeli government declared war to Hamas and began preparing its counter-attack, which began on 27 October. Prior to that, the IDF launched a series of airstrikes throughout the territory and blockaded it, leaving no electricity or supply delivery tracks.
Alongside its invasion into Gaza Strip, Israel has carried out multiple attacks on the territory of Palestinian West Bank, which is partially occupied by the IDF. The goal stated by Israel was to eliminate Hamas militants which fled there from Gaza Strip. The Palestinian Authority, which has not proclaimed itself a supporter of the IDF, is also conducting operations against Hamas militias.
Lebanese militant group Hezbollah started launching rockets into Northern Israel and Golan Heights on October 8, 2023, to support Palestinian forces against Israel. In response, Israel bombed Southern Lebanon, the region of highest Hezbollah presence, as well as engaged in clashes with militants close to the Israeli-Lebanese border.
