Lavon Affair (Operation Susannah)

1954Contested

In July 1954 an Israeli military intelligence cell of Egyptian Jews planted firebombs at British and American sites in Egypt, hoping the blame would fall on Egyptians and keep British troops at Suez. The cell was caught, and the question of who ordered it shook Israeli politics for years.

The story

In July 1954 members of a secret cell run by Israel's military intelligence, Unit 131, planted small incendiary devices in Alexandria and Cairo. Their targets included a post office, the libraries of the U.S. Information Agency, and cinemas owned by British companies. The plan, later code-named Operation Susannah, was to make the attacks look like the work of Egyptian nationalists or communists, so that Britain would doubt Egypt's stability and keep its troops at the Suez Canal base. The bombs did little damage. One device caught fire in an agent's pocket outside a cinema in Alexandria, and Egyptian police soon arrested most of the cell, made up of young Egyptian Jews.

At a Cairo trial two members, Moshe Marzouk and Shmuel Azar, were sentenced to death and hanged in January 1955; an Israeli officer, Max Bennett, killed himself in prison. In Israel the question of who gave the order caused a long crisis. The head of military intelligence, Binyamin Gibli, said Defense Minister Pinhas Lavon had ordered it, while Lavon denied it, and evidence later suggested documents had been altered. Lavon resigned in 1955. The Lavon Affair resurfaced in 1960 and 1961, splitting the ruling party and contributing to David Ben-Gurion's resignation in 1963. In 2005 Israel publicly honored the surviving agents.

Why it mattered

  • The trial and executions in Cairo hardened hostility between Egypt and Israel in the run-up to the Suez Crisis of 1956.
  • The fight over responsibility split Israel's ruling Mapai party and weakened Ben-Gurion's hold on power.
  • The operation is a frequently cited documented case of a state attempting a false flag attack, alongside Gleiwitz and Mainila.

Contested history

Consensus: An Israeli military intelligence cell planted firebombs at British and American sites in Egypt in 1954 to discredit the Egyptian government; it was captured and two members were executed. Israel later acknowledged the operation, but who ordered it remains disputed.

Defense Minister Pinhas Lavon personally gave the orderDebated
Gibli claimed Lavon ordered it; Lavon denied it, and a 1960 ministerial committee effectively cleared him after evidence that documents had been altered. Historians still disagree, and no clear written order has been published.
