Dozens presumed dead after boat capsizes in Congo

Mamboleo said 10 people survived and three bodies had been found, and the search continued for about 37 people.

Deadly boating accidents occur frequently in Congo, where crews often overload small wooden vessels. 

In January, 22 people died on Lake Maî-Ndombe. Last April, six were killed and 64 went missing on Lake Kivu.

Maritime regulations often are not adhered to, Daniel Lwaboshi, director of Congo's Public Riverways Authority, said Monday on state television, adding that another primary driver of such accidents is overloading.
