Check out this article, not for its content (which is horrifying), but so you can look at the picture of the leaking oil well owned by Shell. The picture is from a totally different part of the country than Kano, which is what the story is about.
The Nigerian presidential elections, scheduled for this weekend, are in some jeopardy, partly because the Supreme Court ruled that the vice-president can be on the ballot, and it's far from clear that new ballots can be printed in time.
Meanwhile, results from the first round of elections are more-or-less in. You can see the regional divide between the mostly Muslim north and the mostly Christian south. You can see where the oil is (hint: part of Nigeria's oil-rich delta region is where the results were voided). What a mess.
