The Gaza War, also known as Operation Cast Lead (Hebrew: מִבְצָע עוֹפֶרֶת יְצוּקָה), also known in the Muslim world as the Gaza Massacre (Arabic: مجزرة غزة), and referred to as the Battle of al-Furqan (معركة الفرقان) by Hamas, was a three-week armed conflict between Gaza Strip Palestinian paramilitary groups and the Israel Defense Forces (IDF) that began on 27 December 2008 and ended on 18 January 2009 with a unilateral ceasefire. The conflict resulted in between 1,166 and 1,417 Palestinian and 13 Israeli deaths (including 4 from friendly fire).The Israeli government's stated goal was to stop indiscriminate Palestinian rocket fire into Israel and weapons smuggling into the Gaza strip. Hamas stated its rocket fire, which resumed in November 2008, was in response to an Israeli raid of a tunnel leading from Gaza, which it characterized as a ceasefire violation. Israel said the raid was a preemptive strike against a tunnel they believed would be used to abduct Israeli soldiers guarding the border. In the initial air assault, Israeli forces attacked police stations, military targets including weapons caches and suspected rocket firing teams, as well as political and administrative institutions in the opening assault, striking in the densely populated cities of Gaza, Khan Yunis and Rafah. After hostilities broke out, Palestinian groups fired rockets in retaliation for the aerial bombardments and attacks. The international community considers indiscriminate attacks on civilians and civilian structures that do not discriminate between civilians and military targets as illegal under international law.An Israeli ground invasion began on 3 January. On 5 January, the IDF began operating in the densely populated urban centers of Gaza. During the last week of the offensive (from 12 January), Israel mostly hit targets it had damaged before and struck Palestinian rocket-launching units. Hamas intensified its rocket and mortar attacks against mostly civilian targets in southern Israel, reaching the major cities of Beersheba and Ashdod for the first time during the conflict. Israeli politicians ultimately decided against striking deeper within Gaza amid concerns of higher casualties on both sides and rising international criticism. The conflict ended on 18 January, when the IDF first declared a unilateral ceasefire, followed by Hamas' announcing a one-week ceasefire twelve hours later. The IDF completed its withdrawal on 21 January.According to the Shin Bet, after the conflict, there was a decrease in Palestinian rocket attacks. In September 2009, a UN special mission, headed by the South African Justice Richard Goldstone, produced a report accusing both Palestinian militants and the IDF of war crimes and possible crimes against humanity, and recommended bringing those responsible to justice. In January 2010, the Israeli government released a response criticizing the Goldstone Report and disputing its findings. In 2011, Goldstone wrote that he no longer believed that Israel intentionally targeted civilians in Gaza. The other authors of the report, Hina Jilani, Christine Chinkin, and Desmond Travers, rejected Goldstone's re-assessment. The United Nations Human Rights Council ordered Israel to conduct various repairs of the damages. On 21 September 2012, the United Nations Human Rights Council concluded that 75% of civilian homes destroyed in the attack were not rebuilt.
