At least 34 people are feared drowned after a boat sank off the River Congo.
Police said 76 passengers were rescued from the whale boat – a flat bottomed vessel used to transport people on lakes and rivers.
It was travelling to DR Congo’s capital Kinshasa from Mai Ndombe province, north of the city.
The cause of the accident is not yet known but it is unlikely that passengers were equipped with life jackets.
Accidents are common on the water ways of Congo, often caused by overloading and unsafe vessels.
Many passengers on board the whale boats, which are up to 40 m (130 ft) long and often with two decks, are unable to swim.
The boats are often relied upon as a means of transport, as DR Congo’s road network is poorly maintained.
