At least 20 people were killed and more than a dozen were hurt in a stampede as they rushed to be anointed during a church service in Tanzania.
Thousands of people attended the service at Majengo open ground in the town of Moshi near Mount Kilimanjaro yesterday evening.
Many got crushed after the pastor called them to be anointed with "blessed oil".
The pastor was later arrested for his role in the incident as he sought to leave the country, according to officials.
"Twenty people died and 16 others were injured in the incident," Moshi district commissioner Kippi Warioba told Reuters by telephone.
He said five of the dead were children.
"The stampede occurred when the worshippers were rushing to get anointed with blessed oil," Warioba said.
The service was held by pastor Boniface Mwamposa, who refers to himself as "the apostle".
He had been drawing huge crowds by promising prosperity and cures for diseases to worshippers who step in using what he calls "blessed oil" during his services.
He was arrested today in Tanzania's commercial capital, Dar es Salaam, as he attempted to flee the country, home affairs minister George Simbachawene said.
"Mwamposa tried to flee after this incident, but we arrested him in Dar es Salaam ... he will be held accountable for causing this tragedy," he said.
According to the minister, the stampede took place after the pastor instructed worshippers, who were about 10,000, to rush to one side of the stadium all at once to get anointed.
Authorities fear the death toll could rise due to the size of the crowd and poor lighting 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.
Peter Kilewo, who attended the service, described the scene as "horrible".
He told AFP news agency that people were "trampled on mercilessly, jostling each other with elbows".
He added: "It was like the preacher had thrown bundles of dollars about."
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.
