Dozens of people are missing feared dead in Nigeria after a boat carrying about 200 broke in two and sank, officials say. Most passengers were women and children travelling from neighhouring Niger to the north-western state of Kebbi. One survivor said about 40 people had been rescued, but it is unlikely that many more survivors will be found. Local authorities told the BBC that divers and emergency workers were trying to save others. Five bodies have reportedly been recovered. "Bodies are still being recovered. We can't ascertain the number for now," Yahaya Sarki, a spokesman for the governor of Kebbi, told the Reuters news agency.
