Fred de Sam Lazaro, a reporter for the PBS News Hour, just aired a story, produced for Religion and Ethics Newsweekly about the history of Timbuktu that is being destroyed by fighting today. It's a great story about the fabled history of the city and worth showing your kids when you study Africa.
And here's a great story from NPR about Timbuktu. My colleague, Frances Coffey, just sent me the link. So, between the video and NPR story, the kids should get a great overview of Timbuktu's rich history.
