Israel and the Palestinian Islamist group Hamas are waging their most intense conflict in years.
Here is a timeline of the some of the most important events in many years of confrontation
1987 - Hamas is created at the start of the first Palestinian Intifada, or uprising, against Israel's occupation of the West Bank and Gaza Strip. Two years later, Hamas carries out its first attacks on Israeli military targets, including the kidnap and murder of two Israeli soldiers.
1993 - After years of violence, the first Oslo Accord, aimed at establishing peace between Israel and the Palestinians, is signed. Hamas opposes the peace process, and seeks to derail it with bus bombings and gun attacks in Israel.
2000 - Israel and the Palestinians fail to reach a final agreement in the peace process at a summit in the United States in July 2000. Two months later, Palestinian protests over a visit by Israeli opposition leader Ariel Sharon to the Al-Aqsa mosque compound in East Jerusalem - known to Jews as Temple Mount, because it was the site of ancient Jewish temples, and to Muslims as the Noble Sanctuary - develop into a Second Intifada.
2001-02 - Hamas carries out a series of suicide bombings in Israel, including killing 21 Israelis outside a Tel Aviv disco in June 2001, and 30 Jewish celebrants at a Passover seder dinner in Netanya in March 2022. Four months later, Hamas’s military commander Salah Shehadeh is killed in an Israeli air strike, and Israel starts a siege of Palestinian leader Yasser Arafat's compound in the West Bank city of Ramallah.
March-April 2004 - Israeli air strikes kill Hamas co-founder and spiritual leader, Sheikh Ahmed Yassin, and co-founder and political leader Abdel Aziz al-Rantissi, in Gaza within a month of each other. The Hamas leadership goes into hiding and the identity of Rantissi’s successor is kept secret.
Aug. 15, 2005 - Israeli forces start a unilateral withdrawal from Gaza, captured from Egypt in the 1967 Middle East war, abandoning settlements and leaving the densely populated enclave under the control of the Palestinian Authority.
Jan. 25, 2006 - Hamas wins a majority of seats in a Palestinian legislative election. Israel and United States cut off aid to Palestinians because Hamas refuses to renounce violence and recognise Israel.
June 25, 2006 - Hamas militants capture Israeli conscript Gilad Shalit in a cross-border raid, prompting Israeli air strikes and incursions. Shalit is finally freed over five years later in a prisoner exchange.
June 14, 2007 - Hamas takes over Gaza in a brief civil war, ousting Fatah forces loyal to Palestinian President Mahmoud Abbas, who is based in the West Bank.
Dec 27, 2008 - Israel launches a 22-day military offensive in Gaza after Palestinians fire rockets at the southern Israeli town of Sderot. About 1,400 Palestinians and 13 Israelis are reported killed before a ceasefire is agreed.
Nov 14, 2012 - Israel kills Hamas's military chief of staff, Ahmad Jabari, and eight days of Palestinian militant rocket fire and Israeli air strikes follow.
July-August 2014 - The kidnap and killing of three Israeli teenagers by Hamas leads to a seven-week war in which more than 2,100 Palestinians are reported killed in Gaza and 73 Israelis are reported killed, 67 of them military.
March 2018 - Palestinian protests begin at Gaza's border with Israel and Israeli troops open fire to keep them back. More than 170 Palestinians are reported killed in several months of protests, which also prompt fighting between Hamas and Israeli forces.
May 7, 2021 - After weeks of tension during the Muslim fasting month of Ramadan, Israeli police clash with Palestinian protesters near the Al-Aqsa Mosque over a legal case in which eight Palestinian families face losing their East Jerusalem homes to Jewish settlers.
May 10 - After a weekend of sporadic violence, hundreds of Palestinians are hurt in clashes with Israeli security forces at the Al-Aqsa compound, Islam's third holiest site. After demanding Israel withdraw its security forces from the compound, Hamas fires a barrage of rockets from Gaza into Israel. Israel hits back with air strikes on Gaza.
May 11 - The death toll mounts as the aerial bombardments continue. A 13-story residential building in Gaza collapses after being hit during an Israeli air strike. Palestinian militants launch rockets deep into Israel.
May 12 - The United States announces it will send an envoy to the region. Israel's military kills a senior Hamas commander in Gaza during more hostilities.
May 13 - Israeli air strikes and militant rocket fire continue, and violence worsens in mixed communities of Jews and Arabs in Israel. Synagogues are attacked and clashes break out in some towns.
May 14 - Israel uses warplanes, tanks and artillery against a network of Palestinian militant tunnels under Gaza in an operation that is followed by more Palestinian rocket salvoes.
