The Duraiappa stadium mass grave (also spelled Duraiyappah or Thuraiappa) was discovered and excavated at the Duraiappah Sports Stadium (named after Alfred Duraiappah) in the formerly embattled northern city of Jaffna, Sri Lanka, during a period of relative calm between civil conflicts. The mass grave was unearthed in stages between April 4 and 10 of 1999.[1][2][3][4]
