The 1973 Israeli raid on Lebanon (code-named Operation Spring of Youth) took place on the night of April 9 and early morning of April 10, 1973 when Israel Defense Forces special forces units attacked several Palestine Liberation Organization (PLO) targets in Beirut and Sidon, Lebanon.
The Israeli Sayeret Matkal forces arrived at the Lebanese beaches in Zodiac boats launched from missile ships offshore. Mossad agents awaited the forces on the beaches with cars rented the previous day, and then drove them to their targets and later back to the beaches for extraction.
During the operation, three PLO leaders, surprised at home, were killed, along with other PLO personnel (reports of actual number killed vary from a dozen to 100). Several Lebanese security people and civilian neighbors were also killed. Two Israeli soldiers were killed by defending militants.
