At least 100 people have been killed and dozens injured on Tuesday by widespread floods and landslides caused by heavy rains in the Democratic Republic of the Congo’s capital, Kinshasa.

Prime Minister Jean-Michel Sama Lukonde said officials were still searching for more bodies.

“We came to assess the damage and the primary damage we see is human,” Mr Lukonde said on state television on Tuesday.

Some 12 million people live in the 24 neighbourhoods of Kinshasa hit by the floods, according to local officials who said people were killed, houses submerged and roads ruined.

In the Ngaliema area more than three dozen people died and bodies are still being counted, said the area’s mayor, Alid’or Tshibanda. In another part of town five members from one family were killed, some by electrocution.

“It is a just calamity,” said Pierrot Mantuela. The 30-year-old lost his mother, nine-year-old daughter and three brothers. “It’s sad to lose all the members of my family,” he said. He was spared because he was working on Monday night when the rains began, he said.

Officials said much of the destruction happened in houses built on plots without official permission. “They have no documents. They are chased away but they always come back,” said Dieumerci Mayibazilwanga, the mayor of Mont-Ngafula, of people building unauthorised houses.

In 2019, flooding and landslides killed at least 32 in and around Kinshasa.
