Thunder killed one person in Hai Salaam, Wau on Monday evening during a brief rain.
A neighbour at the scene Hussien Fowad Allah Jabu told Voice of Hope Radio that thunder hit Carlo Mangu Marjan when washing his feet at the compound under the tree.
He said Mangu who was at his seventies died shortly after the incident.
Mr Fowad remembered that in 1996 thunder hit the same house without damages on lives and properties.
The area residents said last year thunder hit a house in the same block and burned it to ashes.
They recalled thunder hitting a house at the same block four years ago.
