On the morning of 17 April 1986, at Heathrow Airport in London, Israeli security guards working for El Al airlines found of Semtex explosive in the bag of Anne-Marie Murphy, a five-month pregnant Irishwoman attempting to board a flight to Tel Aviv with 375 other passengers. In addition, a functioning calculator in the bag was found to be a timed triggering device. She claimed to be unaware of the contents, and that she had been given the bag by her fiancé, Nezar Hindawi, a Jordanian. Murphy maintained that Hindawi had sent her on the flight for the purpose of meeting his parents before marriage.
