April War or Operation Grapes of Wrath

The boy’s death on April 8 effectively signaled the end of the understanding that had prevailed since 1993 and set off Israel’s second full-fledged attack since the end of the war in 1990.
This war took place between April 11 and 26, 1996, during which time Israeli military attacks in Lebanon killed 154 civilians and wounded 351 civilians. It caused the displacement of more than 300,000 civilians, according to Lebanese military records.

The Israeli army destroyed power stations in Jamhour and Bsalim in Beirut’s suburbs, as well as sections of roads and bridges in South Lebanon. For the duration of this war, Israel maintained a steady barrage of artillery, air, and naval fire. Its helicopter and plane attacks reached Beirut, the Beqaa, and South Lebanon. Targets included roads and an electricity station north of Beirut. As of April 13, the Israeli Navy blockaded the ports of Beirut, Saida, and Sour.

The operation ended after a new, written understanding was reached between the warring parties on April 26, 1996, stipulating the same basis as the 1993 understanding; in essence, provisions for the protection of the civilians. But unlike the previous one, this one was put in writing and made public. It also established a monitoring group representing the United States, France, Syria, Lebanon, and Israel to supervise its implementation.
Both parties violated this understanding, however, on several occasions, before Israel withdrew from South Lebanon in May 2000.
