April 19 (UPI) -- A wall collapsed during a church service in South Africa late Thursday and killed 13 worshipers, officials said.
Officials believe heavy rains caused the front wall to collapse at the Pentecostal Holiness Church in Ndlangubo, in South Africa's KwaZulu-Natal province. Emergency personnel said nearly three dozen people were injured, at least six critically.
The rural church on South Africa's eastern coastline was filled with congregants Thursday night for the start of a Passover service to begin Easter week events.
A preliminary investigation cited the heavy rains as a primary factor in the structural collapse. KwaZulu-Natal Premier Willies Mchunu called for an investigation into the safety of the building.
"It is an act of nature, an act of God," municipal official Lennox Mabaso said.
Emergency officials were expected to visit the church site Friday.
