The Walisongo school massacre is the name given to a series of attacks by Christian militants on the 28 May 2000 upon several predominantly Muslim villages around Poso town, Central Sulawesi, Indonesia as part of a broader sectarian conflict in the Poso region. Officially the total number killed in the attacks is 165, but there is no definite figure of how many died. The number of dead is believed to be greater than the 39 calculated from bodies later discovered in 3 mass graves, and equal to or below the 191 quoted by Muslim sources. The massacre is named for the Pesantren Walisongo boarding school in Sintuwu Lemba where the most high profile murders occurred. Three leaders of local Christian militia groups were later convicted and executed in 2006 for crimes committed during the massacre
