The health and humanitarian affairs ministry also says, 267 people were rescued.
Authorities believe that, about 50 people are still missing, although they could not retrieve the passenger manifest as the boat’s owner also drowned.
The accident happened in the early hours of Sunday when a wooden vessel sank in the Lulanga River in western DRC.
Transport Minister Mark Ekila said that there have been 88 boat accidents this year alone, 80% of which involved old wooden vessels or vessels sailing at night, in breach of regulations.
The government has announced that it is working on tighter measures, including banning dilapidated vessels and separating people from travelling together, with cargo and pets.
