Eight people including an Irish missionary and a 3-year-old child remained missing Monday after gunmen stormed an orphanage in Haiti, the latest attack in an area controlled by a powerful collection of armed gangs.

Gena Heraty was among several people -- including a three-year-old child -- taken in the early hours of Aug. 3 after gunmen breached the Saint-Hélène orphanage in Kenscoff, near Haiti's capital of Port-au-Prince.

Ms Heraty, who has worked in the Caribbean country for decades, was among eight people, including a three-year-old child, taken from an orphanage on Sunday.
