Dozens of people were missing in northwest Nigeria on Wednesday after an overloaded boat ferrying around 160 passengers sank in the Niger River, a local official said.
The boat left central Niger state and was heading to northwest Kebbi state when it split and sank, Abdullahi Buhari Wara, administrative head of Ngaski district said.
"A rescue operation is underway but only 22 survivors and one dead body have been recovered," Wara said. "We are talking of around 140 passengers still missing."
Boat capsizals are common on Nigerian waterways mostly due to overcrowding and lack of maintenance, particularly in the annual rainy season.
Wara blamed the Kebbi accident on overloading as the boat was meant to ferry not more than 80 passengers.
The vessel was also loaded with bags of sand from a gold mine, the official said.
Early this month 30 people drowned when an overloaded boat capsized in central Niger state.
The boat ferrying 100 local traders split into two after hitting a stump during a storm as they were returning from a local market, according to emergency officials.
