At least 19 people died when heavy winds caused a boat to capsize on Democratic Republic of Congos Lake Mai-Ndombe, the governor of Mai-Ndombe province said on Saturday.
The boat had left the village of Kiri for the capital Kinshasa when it capsized on Thursday night, local government and civil society sources said.
River boats are the main form of transport in many rural parts of Congo, but vessels are often outdated and accidents are frequent.
