The United States says Nigerian forces battling Boko Haram jihadists need a change of mindset to overcome an evolving guerrilla threat.

Speaking on the sidelines of an African security summit, Lieutenant-Colonel Sean McClure, the US defence attache in Abuja said Boko Haram’s tactics which began from improvised explosive devices to hiding within the local population, necessitate a shift away from conventional strategies.

Nigeria, Africa’s most populous country with more than 180 million people, has been fighting Boko Haram since 2009 and has repeatedly claimed to have defeated the group.
