People stand by the wreckage of a car that has been blown up by suspected Boko Haram militants in Nigeria's troubled northeastern city of Maiduguri on March 25, 2014, killing five police officers, while a separate blast killed three. The attacks were the latest to hit the Borno state capital, which is the epicentre of Boko Haram's brutal insurgency which has killed thousands since 2009, including more than 700 this year.
