MAIDUGURI, Nigeria, May 12 (Reuters) - The leader of the Nigerian Islamist rebel group Boko Haram has offered to release more than 200 schoolgirls abducted by his fighters last month in exchange for its members being held in detention, according to a video posted on YouTube on Monday.
The search for the girls intensified as a senior U.S. administration official said the United States deployed manned surveillance aircraft over Nigeria and was sharing satellite imagery with the Nigerian government.
