Kidnapping and killing of Margaret Hassan
Margaret Hassan (née Fitzsimons; 18 April 1945 – 8 November 2004) was an Irish aid worker who had worked in Iraq for many years until she was abducted by unidentified assailants in Baghdad during the Iraqi insurgency. Her captors subsequently filmed and released a video of her stating that she was living her "last hours" before she pleaded for the withdrawal of British troops from Iraq; she has not been seen since, and her remains were never recovered.
