Hunt for Chibok Girls is Unlikely to have a Happy Ending" - by: Joe Brock

(Reuters) - Nigeria's hunt for more than 200 abducted schoolgirls is not all that it seems. In public, an international operation is gathering pace while behind the scenes, officials say it is unlikely to deliver the success that global opinion demands.

The United States and Britain are helping Nigerian forces in the effort to liberate the girls taken from their school in Borno state a month ago by Boko Haram Islamist militants.

The pressure for results is huge, with the likes of Michelle Obama and film star Angelina Jolie supporting a social media campaign operating under the Twitter tag ‪#‎BringBackOurGirls‬.

Washington has sent surveillance aircraft as well as assigning medical, intelligence, counter-terrorism and communications advisers to the mission.
