The conflict began when Hezbollah militants purposely fired rockets at Israeli border towns as a diversion for an anti-tank missile attack on two armored Humvees patrolling the Israeli side of the border fence. Of the seven Israeli soldiers in the two jeeps, two were wounded, three were killed, and two were kidnapped and taken to Lebanon. Five more were killed in a failed Israeli rescue attempt. Israel responded with massive airstrikes and artillery fire on targets in Lebanon that damaged Lebanese civilian infrastructure, including Beirut's Rafic Hariri International Airport (which Israel alleged that Hezbollah used to import weapons and supplies), an air and naval blockade, and a ground invasion of southern Lebanon. Hezbollah then launched more rockets into northern Israel and engaged the Israel Defense Forces (IDF) in guerrilla warfare from hardened positions.
The conflict killed over a thousand people, widely reported to be mostly Lebanese civilians, severely damaged Lebanese civil infrastructure, and displaced approximately one million Lebanese and 300,000–500,000 Israelis, although most were able to return to their homes. After the ceasefire, some parts of Southern Lebanon remained uninhabitable due to Israeli unexploded cluster bomblets.
On 11 August 2006, the United Nations Security Council unanimously approved UN Resolution 1701 in an effort to end the hostilities. The resolution, which was approved by both Lebanese and Israeli governments the following days, called for disarmament of Hezbollah, for withdrawal of Israel from Lebanon, and for the deployment of Lebanese soldiers and an enlarged United Nations Interim Force in Lebanon (UNIFIL) force in southern Lebanon. The Lebanese army began deploying in southern Lebanon on 17 August 2006. The blockade was lifted on 8 September 2006. On 1 October, 2006, most Israeli troops withdrew from Lebanon, though the last of the troops continue to occupy the border-straddling village of Ghajar. In the time since the enactment of UNSCR 1701 both the Lebanese government and UNIFIL have stated that they will not disarm Hezbollah. The remains of the two kidnapped soldiers, whose fates were unknown, were returned to Israel on 16 July 2008 as part of a prisoner exchange.
The Palestine Liberation Organization (PLO) had engaged in cross-border attacks from southern Lebanon into Israel as far back as 1968, and the area became a significant base following the arrival of the PLO leadership and its Fatah brigade after their 1971 expulsion from Jordan. Demographic tensions were running high over the Lebanese National Pact, which divided governmental powers among religious groups, leading in part to the Lebanese Civil War (1975–1990). Concurrently, Syria began a 29 year military occupation. Israel's 1978 invasion of Lebanon failed to stem the Palestinian attacks, but Israel invaded Lebanon again in 1982 and forcibly expelled the PLO. Israel withdrew to a borderland buffer zone in southern Lebanon, held with the aid of proxy militants in the South Lebanon Army (SLA). In 1985, a Shi'a militant group calling itself Hezbollah declared an armed struggle to end the Israeli occupation of Lebanese territory. When the Lebanese civil war ended and other warring factions agreed to disarm, Hezbollah and the SLA refused. Combat with Hezbollah led to a collapse of the SLA.
When in 2000 Israel withdrew from Southern Lebanon to the UN designated border, Hezbollah immediately followed in. Citing Israeli control of the disputed Shebaa farms region and the incarceration of Lebanese prisoners in Israel, Hezbollah continued cross border attacks, and used the tactic of seizing soldiers from Israel as leverage for a prisoner exchange in 2004, though it also continues to call for Israel's destruction.
Beginning of conflict
At around 8:07 AM local time (05:07 UTC) on 12 July 2006, Hezbollah launched diversionary rocket attacks toward Israeli military positions near the coast and near the border village of Zar'it as well as on the Israeli town of Shlomi and other villages. At the same time, a Hezbollah ground contingent crossed the border into Israeli territory and attacked two Israeli armoured Humvees patrolling on the Israeli side of the Israel-Lebanon border, near Zar'it, killing three, injuring two, and kidnapping two Israeli soldiers (master sergeant Ehud Goldwasser and first sergeant Eldad Regev). Five more Israeli soldiers were killed later and a tank was destroyed on the Lebanese side of the border during an unsuccessful attempt to rescue the two kidnapped soldiers.
Hezbollah named the attack "Operation Truthful Promise" after leader Hassan Nasrallah's public pledges over the prior year and a half to seize Israeli soldiers and swap them for four Lebanese held by Israel:
- Samir Kuntar (a Lebanese citizen captured during a terrorist attack in 1979, convicted of murdering civilians and a police officer);
- Nasim Nisr (an Israeli-Lebanese citizen tried and convicted for spying by Israel);
- Yahya Skaf (a Lebanese citizen whom Hezbollah claims was arrested in Israel, Israel denies);
- Ali Faratan (another Lebanese citizen whom Hezbollah claims to be held in Israel).
Nasrallah claimed that Israel had broken a previous deal to release these prisoners, and since diplomacy had failed, violence was the only remaining option. Nasrallah declared: "No military operation will return the Israeli captured soldiers…The prisoners will not be returned except through one way: indirect negotiations and a trade of prisoners."
Israeli Prime Minister Ehud Olmert described the seizure of the soldiers as an "act of war" by the sovereign country of Lebanon, stating that "Lebanon will bear the consequences of its actions" and promising a "very painful and far-reaching response." Israel blamed the Lebanese government for the raid, as it was carried out from Lebanese territory and Hezbollah had two ministers serving in the Lebanese cabinet at that time. In response, Lebanese Prime Minister Fouad Siniora denied any knowledge of the raid and stated that he did not condone it. An emergency meeting of the Lebanese government reaffirmed this position.
The Israel Defense Forces attacked targets within Lebanon with artillery and airstrikes hours before the Israeli Cabinet met to discuss a response. The Israeli aviation bombed several areas in Lebanon (bridges and roads, the Beirut airport), resulting in 44 civilian deaths.
Later that same day (12 July 2006), the Cabinet decided to authorize the Prime Minister, the Defense Minister and their deputies to pursue the plan which they had proposed for action within Lebanon. The decision also emphasized Prime Minister Olmert's demand that the Israeli Defense Force avoid civilian casualties whenever possible. Israel's chief of staff Dan Halutz said, "if the soldiers are not returned, we will turn Lebanon's clock back 20 years" while the head of Israel's Northern Command Udi Adam said, "this affair is between Israel and the state of Lebanon. Where to attack? Once it is inside Lebanon, everything is legitimate -- not just southern Lebanon, not just the line of Hezbollah posts." On 12 July 2006, the Israeli Cabinet promised that Israel would "respond aggressively and harshly to those who carried out, and are responsible for, today's action". The Cabinet's communiqué stated, in part, that the "Lebanese Government [was] responsible for the action that originated on its soil." A retired Israeli Army Colonel explained that the rationale behind the attack was to create a rift between the Lebanese population and Hezbollah supporters by exacting a heavy price from the elite in Beirut.
On 16 July, the Israeli Cabinet released a communiqué explaining that, although Israel had engaged in military operations within Lebanon, its war was not against the Lebanese government. The communiqué stated: "Israel is not fighting Lebanon but the terrorist element there, led by Nasrallah and his cohorts, who have made Lebanon a hostage and created Syrian- and Iranian-sponsored terrorist enclaves of murder."
When asked in August about the proportionality of the response, Prime Minister Olmert stated that the "war started not only by killing eight Israeli soldiers and abducting two but by shooting Katyusha and other rockets on the northern cities of Israel on that same morning. Indiscriminately." He added "no country in Europe would have responded in such a restrained manner as Israel did."
