A boat ferrying about 200 people capsized in the northwestern Nigerian state of Kebbi on Wednesday but the number of casualties remains unclear, a state spokesman said.
The wooden boat capsized near Wara, a town on the shores of Kainji Lake, part of the Niger River, said Yahaya Sarki, a spokesman the governor of Kebbi.
It had about 200 passengers on board, coming from the neighbouring Nigerian state of Niger.
"Bodies are still being recovered. We can't ascertain the number for now," Sarki said.
One survivor, Buhari Abubakar, said about 40 people have been rescued so far, though many of the other passengers, mostly women and children, are still missing.
