Operation Defensive Shield ( ) was a 2002 Israeli military operation in the West Bank, carried out amidst the Second Intifada. Lasting for just over a month, it was the largest combat operation in the West Bank since the 1967 Arab–Israeli War, when Israel seized the territory from Jordan. Israel's stated goal for the escalation was to stop Palestinian terrorist attacks; the operation was launched two days after the Passover massacre, in which a Palestinian suicide bomber attacked the Park Hotel in Netanya, killing 30 civilians while injuring 140 more. The operation began with an Israeli incursion into Ramallah, where Yasser Arafat was placed under siege at his compound. This was followed by successive incursions into the six largest cities in the West Bank and their surrounding localities. Israel's military moved into Tulkarm and Qalqilya on April 1, into Bethlehem on April 2, and into Jenin and Nablus on April 3. From April 3–21, strict curfews were enforced on civilian populations in the West Bank, and international personnel had their movement restricted — including, at times, prohibition of entry to humanitarian and medical personnel as well as human rights monitors and journalists. In May 2002, Israeli troops withdrew from Palestinian cities in the West Bank while maintaining cordons of troops around certain towns and villages, and also continued carrying out raids on Palestinian-populated areas. The United Nations' report on the subject states: "Combatants on both sides conducted themselves in ways that, at times, placed civilians in harm's way. Much of the fighting during Operation Defensive Shield occurred in areas heavily populated by civilians and in many cases heavy weaponry was used." Background The Israeli–Palestinian conflict escalated during the Second Intifada. In January and February 2002, 71 people were killed on all sides during attacks from Palestinian terrorists and the Israeli army. March and April 2002 saw a dramatic increase in attacks against Israelis by Palestinian militants such as Hamas, Islamic Jihad and the Fatah-affiliated Al-Aqsa Martyrs' Brigades. In addition to numerous shooting and grenade attacks, fifteen suicide bombings were carried out in March, an average of one suicide bombing every two days. March 2002 became known in Israel as "Black March". The large number of attacks severely disrupted daily life in Israel. The first wave of Israeli incursions took place between 27 February and 14 March. Following nine attacks by Palestinian militants between March 2–5, the Israeli cabinet decided to
