El Al
A terrorist attack was foiled on 18 April 1986 in what became known as the Hindawi Affair. A pregnant Irishwoman named Anne-Marie Murphy was about to board an El Al flight at London's Heathrow airport when her bag was found to contain three pounds of plastic explosives. These had been planted by her fiancé Nezar Hindawi, who was booked on a different flight. Hindawi was jailed for 45 years, the longest sentence (short of a life sentence) ever delivered by a British court. There was evidence that Syrian officials were involved and as a result, Britain cut off diplomatic relations with Syria.
