A lightning strike killed at least 16 people and injured dozens more at a Seventh-Day Adventist church in Rwanda on Saturday, an official said.
Most of the victims died instantly when lightning hit the church in the southern district of Nyaruguru, local mayor Habitegeko Francois told AFP.
Two people died from their injuries, and 140 people were rushed to hospital and health centres.
Lightning also killed a student in the area on Friday, the mayor said.
