The floods were sparked by torrential rains and ripped through the Kasaba village in the Sud Kivu province during the night of Thursday-Friday, Bernard Akili, a regional official, told AFP.

Torrential rains caused the Kasaba river to burst its banks overnight, with the rushing waters "carrying everything in their path, large stones, large trees and mud, before razing the houses on the edge of the lake," he said.

"The victims who died are mainly children and elderly," he said, adding that 28 people were injured and some 150 homes were destroyed.

Sammy Kalonji, the regional administrator, said the torrent killed at least 104 people and caused "enormous material damage."

Another local resident told AFP that some 119 bodies had been found by Saturday.

The village, which sits on the Tanganyika lake and is only accessible by the lake, does not have internet service, a local humanitarian worker told AFP

Such natural disasters are frequent in the DRC, particularly on the shores of the great lakes in the east of the country, with the surrounding hills weakened by deforestation.

In 2023, floods killed 400 people in several communities located on the shores of Lake Kivu, in South Kivu province.
