In October 1972, Israel obtained intelligence on the home addresses of three top PLO officials in Beirut: •
Muhammad Youssef al-Najjar (Abu Youssef) – an operations leader in
Black September, the group responsible for the 1972
Munich massacre. He was also a PLO veteran, previously head of the Lebanese
Fatah branches, head of Fatah internal intelligence organization. His latest duties were head of the PLO's political department and one of
Yasser Arafat's deputies (third in line of Fatah's leadership). •
Kamal Adwan – a PLO chief of operations, responsible for armed attacks against Israeli targets. •
Kamal Nasser – PLO spokesman and member of the PLO Executive Committee. Najjar, Adwan, and Nasser lived near one another in a pair of seven-story buildings on Verdun Street in a fashionable area of West Beirut. These buildings were residential housing for both British and Italian families along with Arab families. One building housed Al-Najjar, and a building across the street housed Adwan and Nasser. Intelligence had also been obtained on the address of
Khalil al-Wazir, the PLO's second-in-command, but he lived further away from the three others. In addition to information about their residences, high-grade intelligence had also been amassed on other PLO targets in Lebanon such as weapons workshops, command posts, and offices. It was decided to assassinate Najjar, Adwan, and Nasser. The
Mossad subsequently deployed
Yael Man, a female agent codenamed Nielsen to Beirut in January 1973 to amass further intelligence so that an assassination operation could be planned. She arrived in Lebanon under the cover story that she was there to conduct research for a television series on the life of
Lady Hester Stanhope which she was planning on writing. She rented an apartment in a building exactly opposite the two buildings where Najjar, Adwan, and Nasser lived and clandestinely photographed potential landing areas and the target buildings, also meticulously recording the routines of those in the buildings. Before the mission, the forces trained using similar apartments in northern
Tel Aviv. They also practiced cross-dressing and walking around disguised as lovers. Meanwhile, Mossad agents in Beirut gathered additional intelligence for the raid. Nielsen selected the private beach of the Sands Hotel as the landing site since access was restricted to guests and it was close to the hotel's parking lot, where the commandos could be picked up by Mossad agents. Brigadier General
Emmanuel Shaked, the commander of the IDF's infantry and paratrooper forces, was placed in overall command of the operation. On April 6, 1973, six Mossad operatives arrived in Beirut on counterfeit British, German, and Belgian passports. They checked into the Sands Hotel, rented cars, and parked them in the hotel's parking lot. ==The operation==
