Rescue workers in northern Nigeria are searching for more than 40 missing passengers after a boat accident in Sokoto state, the authorities have said.

The National Emergency Management Agency (Nema) said the boat was carrying more than 50 people to a local market when it capsized in the River Goronyo on Sunday.

A Sokoto official told the BBC that four people have been found alive. Nema said it was "intensifying efforts alongside local authorities to locate [those] still missing".

Boat accidents occur regularly in Nigeria due to overcrowding, poorly maintained boats and the failure to enforce safety regulations.

In December 2024, 54 bodies were recovered from the River Niger after a boat that may have been carrying more than 200 passengers capsized.
