2023 – The 2023 Israel–Hamas war is declared following the Hamas attack the day prior. An armed conflict between Israel and Hamas-led Palestinian militant groups has been taking place in the Gaza Strip and Israel since 7 October 2023. It is the fifth war of the Gaza–Israel conflict since 2008, and the most significant military engagement in the region since the Yom Kippur War in 1973. It is the deadliest war for Palestinians in the history of the Israeli–Palestinian conflict. The war began when Hamas-led militant groups launched a surprise attack on Israel on 7 October, which involved a rocket barrage and a few thousand militants breaching the Gaza–Israel barrier, attacking Israeli civilian communities and military bases. During this attack, 1,195 Israelis and foreign nationals were killed, including 815 civilians. In addition, 251 Israelis and foreigners were taken captive into Gaza, with the stated goal to force Israel to release Palestinian prisoners and detainees. Hamas said its attack was in response to Israel's continued occupation, blockade of Gaza, expansion of settlements, Israel's disregard for international law, as well as alleged threats to the Al-Aqsa Mosque and the general plight of Palestinians. After clearing militants from its territory, Israel launched one of the most destructive bombing campaigns in modern history and invaded Gaza on 27 October with the stated objectives of destroying Hamas and freeing hostages. The war continues to have significant regional and international repercussions.
