A Boat with 150 passengers has been reported capsized in River Niger, at the remote area of Lolo village in Kebbi state.
Emergency officials say they managed to rescue 84 people on board, but another 30 of the total 150 passengers remained unaccounted for.
They blamed the accident on overloading of the boat, which had been travelling from neighbouring Niger.
Nigeria has seen many boats capsize due to poorly maintained overcrowded boats.
The accident happened on Wednesday morning, but details only first started emerging on Friday.
The boat had been carrying traders across the border from Gaya, in the Dosso region of Niger. They were planning to attend a village market in Nigeria.
The coordinator of National Emergency Management (NEMA), Suleiman Mohammed Karim, said the boat had a capacity of 70 passengers but survivors said 150 people plus their goods were on board.
Speaking about the remaining missing people the Coordinator said “Having spent two days on the water, we presume they are all dead.”
