(NBC News) Boko Haram forces appear poised to attack Maiduguri, a city of 2 million in northeast Nigeria -- meaning that 200,000 Christians could be at risk of slaughter by the Islamist terror group, say U.S. intelligence officials and experts on Nigeria.
"An attack on Madiguri is very likely," said J. Peter Pham, director of the Africa Project at the Atlantic Council, echoing U.S. intelligence officials. Pham believes, as do other experts, that Boko Haram has already placed "sleeper cells" among the tide of refugees who have fled the group's murderous rampage through Africa's most populous nation. "They've done it everywhere else they've gone," said Pham. "So why not Maiduguri?"
