The Droppin Well bombing or Ballykelly bombing occurred on 6 December 1982, when the Irish National Liberation Army (INLA) exploded a time bomb at a disco in Ballykelly, Northern Ireland. The disco, known as the Droppin Well, was targeted because it was frequented by British Army soldiers from the nearby Shackleton Barracks. The bomb killed eleven soldiers and six civilians; 30 people were injured.
