Nigerian health officials say 28 children have been killed by lead poisoning from illegal gold mining in a remote west-central village. Dozens more are sick.
The outbreak is in the same region where doctors still are treating children from a 2010 mass poisoning in Zamfara state that killed 400 kids and left many paralyzed and blind because of delays in government funding for a cleanup.
Doctors Without Borders said Friday it has cured half the 5,500 infected there and has started closing clinics.
Junior Health Minister Fidelis Nwankwo said Thursday all those newly infected in neighboring Niger state are under 5 with a 43 percent fatality rate. He says they have started treatment.
It's not known when a clean-up is planned. Villagers also have to learn safe mining practices.
