A woman leading protests over the abduction of more than 200 girls in Nigeria has been detained on the orders of the president's wife, activists say. Naomi Mutah took part in a meeting called by First Lady Patience Jonathan and was then taken to a police station, they say. Mrs Jonathan reportedly felt slighted that the mothers of the abducted girls had sent Ms Mutah to the meeting. Analysts say Mrs Jonathan is a politically powerful figure. Ms Mutah, a representative of the Chibok community where the girls were seized from their school more than two weeks ago, last week organised a protest outside parliament in the capital, Abuja. http://www.bbc.com/news/world-africa-27283278
