SIX people have drowned and scores more are missing after a boat carrying at least 200 people sank in the Forcados River in south-east Nigeria, press reports said on Tuesday. The accident took place late on Sunday near Burutu in the swamps south of the troubled oil town of Warri, the reports said, quoting police and survivors. At least 200 people, many of them women and children returning from a market, were on the boat. The captain complained before sailing that the boat was overloaded but was persuaded to continue, one report said.
