I want to know the answer to the following question:
How many people had Boko Haram killed by May 2014?
All the background I'm provided with is that "At the same time, neighbouring countries, Benin, Chad, Cameroon and Niger joined Nigeria in a united effort to combat Boko Haram in the aftermath of a world media highlighted kidnapping of 276 schoolgirls and the spread of Boko Haram attacks to these countries.". Is that enough to answer the question?
Answer: no
