The Lavon affair was a failed Israeli covert operation, codenamed Operation Susannah, conducted in Egypt in the summer of 1954. As part of a false flag operation, a group of Egyptian Jews were recruited by Israeli military intelligence to plant bombs inside Egyptian-, American-, and British-owned civilian targets: cinemas, libraries, and American educational centers. The bombs were timed to detonate several hours after closing time. The attacks were to be blamed on the Muslim Brotherhood, Egyptian communists, "unspecified malcontents", or "local nationalists" with the aim of creating a climate of sufficient violence and instability to induce the British government to retain its occupying troops in Egypt's Suez Canal zone. The operation caused no casualties among the population, but resulted in the deaths of four operatives. The overseer of the operation allegedly informed the Egyptians, after which 11 suspected operatives were arrested. Two committed suicide after being captured, two were executed by the Egyptian authorities, two of them were acquitted at trial, and the remaining five received prison terms ranging from 7 years to life in prison.

A covert operation or undercover operation is a military or police operation involving a covert agent or troops acting under an assumed cover to conceal the identity of the party responsible. Some of the covert operations are also clandestine operations which are performed in secret and meant to stay secret, though many are not.
