DAR ES SALAAM: At least 20 people have been killed and over a dozen injured in a stampede during a church service at a stadium in northern Tanzania, a government official said on Sunday. Hundreds of people packed a stadium on Saturday evening in Moshi town near the slopes of Mount Kilimanjaro and crushed each other as they rushed to get anointed with “blessed oil.” “Twenty people died and 16 others were injured in the incident,” Moshi district commissioner Kippi Warioba told Reuters by telephone. Five of those killed were children, he said. “The stampede occurred when the worshippers were rushing to get anointed with blessed oil,” Warioba said. Pastor Boniface Mwamposa has been drawing huge crowds by promising prosperity and cure for disease to worshippers who walk on what he describes as “blessed oil” during his church services. Authorities fear the death toll could rise due to the size of the crowd and dark conditions when the stampede occurred. “The incident took place at night and there were many people, so there is a possibility that more casualties could emerge. We are still assessing the situation,” Warioba said. Tanzania has seen a rise in the number of “prosperity gospel” pastors in recent years, who promise to lift people out of poverty and perform what they call miracle cures. Thousands of people in the nation of 55 million flock to Pentecostal churches, whose main source of income is “tithe,” the 10% or so of income that worshippers are asked to contribute.
